what chapters are in a dissertation

Dissertation Structure & Layout 101: How to structure your dissertation, thesis or research project.

By: Derek Jansen (MBA) Reviewed By: David Phair (PhD) | July 2019

So, you’ve got a decent understanding of what a dissertation is , you’ve chosen your topic and hopefully you’ve received approval for your research proposal . Awesome! Now its time to start the actual dissertation or thesis writing journey.

To craft a high-quality document, the very first thing you need to understand is dissertation structure . In this post, we’ll walk you through the generic dissertation structure and layout, step by step. We’ll start with the big picture, and then zoom into each chapter to briefly discuss the core contents. If you’re just starting out on your research journey, you should start with this post, which covers the big-picture process of how to write a dissertation or thesis .

*The Caveat *

In this post, we’ll be discussing a traditional dissertation/thesis structure and layout, which is generally used for social science research across universities, whether in the US, UK, Europe or Australia. However, some universities may have small variations on this structure (extra chapters, merged chapters, slightly different ordering, etc).

So, always check with your university if they have a prescribed structure or layout that they expect you to work with. If not, it’s safe to assume the structure we’ll discuss here is suitable. And even if they do have a prescribed structure, you’ll still get value from this post as we’ll explain the core contents of each section.  

Overview: S tructuring a dissertation or thesis

• Acknowledgements page
• Abstract (or executive summary)
• Table of contents , list of figures and tables
• Chapter 1: Introduction
• Chapter 2: Literature review
• Chapter 3: Methodology
• Chapter 4: Results
• Chapter 5: Discussion
• Chapter 6: Conclusion
• Reference list

As I mentioned, some universities will have slight variations on this structure. For example, they want an additional “personal reflection chapter”, or they might prefer the results and discussion chapter to be merged into one. Regardless, the overarching flow will always be the same, as this flow reflects the research process , which we discussed here – i.e.:

• The introduction chapter presents the core research question and aims .
• The literature review chapter assesses what the current research says about this question.
• The methodology, results and discussion chapters go about undertaking new research about this question.
• The conclusion chapter (attempts to) answer the core research question .

In other words, the dissertation structure and layout reflect the research process of asking a well-defined question(s), investigating, and then answering the question – see below.

To restate that – the structure and layout of a dissertation reflect the flow of the overall research process . This is essential to understand, as each chapter will make a lot more sense if you “get” this concept. If you’re not familiar with the research process, read this post before going further.

Right. Now that we’ve covered the big picture, let’s dive a little deeper into the details of each section and chapter. Oh and by the way, you can also grab our free dissertation/thesis template here to help speed things up.

The title page of your dissertation is the very first impression the marker will get of your work, so it pays to invest some time thinking about your title. But what makes for a good title? A strong title needs to be 3 things:

• Succinct (not overly lengthy or verbose)
• Specific (not vague or ambiguous)
• Representative of the research you’re undertaking (clearly linked to your research questions)

Typically, a good title includes mention of the following:

• The broader area of the research (i.e. the overarching topic)
• The specific focus of your research (i.e. your specific context)
• Indication of research design (e.g. quantitative , qualitative , or  mixed methods ).

For example:

A quantitative investigation [research design] into the antecedents of organisational trust [broader area] in the UK retail forex trading market [specific context/area of focus].

Again, some universities may have specific requirements regarding the format and structure of the title, so it’s worth double-checking expectations with your institution (if there’s no mention in the brief or study material).

Acknowledgements

This page provides you with an opportunity to say thank you to those who helped you along your research journey. Generally, it’s optional (and won’t count towards your marks), but it is academic best practice to include this.

So, who do you say thanks to? Well, there’s no prescribed requirements, but it’s common to mention the following people:

• Your dissertation supervisor or committee.
• Any professors, lecturers or academics that helped you understand the topic or methodologies.
• Any tutors, mentors or advisors.
• Your family and friends, especially spouse (for adult learners studying part-time).

There’s no need for lengthy rambling. Just state who you’re thankful to and for what (e.g. thank you to my supervisor, John Doe, for his endless patience and attentiveness) – be sincere. In terms of length, you should keep this to a page or less.

Abstract or executive summary

The dissertation abstract (or executive summary for some degrees) serves to provide the first-time reader (and marker or moderator) with a big-picture view of your research project. It should give them an understanding of the key insights and findings from the research, without them needing to read the rest of the report – in other words, it should be able to stand alone .

For it to stand alone, your abstract should cover the following key points (at a minimum):

• Your research questions and aims – what key question(s) did your research aim to answer?
• Your methodology – how did you go about investigating the topic and finding answers to your research question(s)?
• Your findings – following your own research, what did do you discover?
• Your conclusions – based on your findings, what conclusions did you draw? What answers did you find to your research question(s)?

So, in much the same way the dissertation structure mimics the research process, your abstract or executive summary should reflect the research process, from the initial stage of asking the original question to the final stage of answering that question.

In practical terms, it’s a good idea to write this section up last , once all your core chapters are complete. Otherwise, you’ll end up writing and rewriting this section multiple times (just wasting time). For a step by step guide on how to write a strong executive summary, check out this post .

Table of contents

This section is straightforward. You’ll typically present your table of contents (TOC) first, followed by the two lists – figures and tables. I recommend that you use Microsoft Word’s automatic table of contents generator to generate your TOC. If you’re not familiar with this functionality, the video below explains it simply:

If you find that your table of contents is overly lengthy, consider removing one level of depth. Oftentimes, this can be done without detracting from the usefulness of the TOC.

Right, now that the “admin” sections are out of the way, its time to move on to your core chapters. These chapters are the heart of your dissertation and are where you’ll earn the marks. The first chapter is the introduction chapter – as you would expect, this is the time to introduce your research…

It’s important to understand that even though you’ve provided an overview of your research in your abstract, your introduction needs to be written as if the reader has not read that (remember, the abstract is essentially a standalone document). So, your introduction chapter needs to start from the very beginning, and should address the following questions:

• What will you be investigating (in plain-language, big picture-level)?
• Why is that worth investigating? How is it important to academia or business? How is it sufficiently original?
• What are your research aims and research question(s)? Note that the research questions can sometimes be presented at the end of the literature review (next chapter).
• What is the scope of your study? In other words, what will and won’t you cover ?
• How will you approach your research? In other words, what methodology will you adopt?
• How will you structure your dissertation? What are the core chapters and what will you do in each of them?

These are just the bare basic requirements for your intro chapter. Some universities will want additional bells and whistles in the intro chapter, so be sure to carefully read your brief or consult your research supervisor.

If done right, your introduction chapter will set a clear direction for the rest of your dissertation. Specifically, it will make it clear to the reader (and marker) exactly what you’ll be investigating, why that’s important, and how you’ll be going about the investigation. Conversely, if your introduction chapter leaves a first-time reader wondering what exactly you’ll be researching, you’ve still got some work to do.

Now that you’ve set a clear direction with your introduction chapter, the next step is the literature review . In this section, you will analyse the existing research (typically academic journal articles and high-quality industry publications), with a view to understanding the following questions:

• What does the literature currently say about the topic you’re investigating?
• Is the literature lacking or well established? Is it divided or in disagreement?
• How does your research fit into the bigger picture?
• How does your research contribute something original?
• How does the methodology of previous studies help you develop your own?

Depending on the nature of your study, you may also present a conceptual framework towards the end of your literature review, which you will then test in your actual research.

Again, some universities will want you to focus on some of these areas more than others, some will have additional or fewer requirements, and so on. Therefore, as always, its important to review your brief and/or discuss with your supervisor, so that you know exactly what’s expected of your literature review chapter.

Now that you’ve investigated the current state of knowledge in your literature review chapter and are familiar with the existing key theories, models and frameworks, its time to design your own research. Enter the methodology chapter – the most “science-ey” of the chapters…

In this chapter, you need to address two critical questions:

• Exactly HOW will you carry out your research (i.e. what is your intended research design)?
• Exactly WHY have you chosen to do things this way (i.e. how do you justify your design)?

Remember, the dissertation part of your degree is first and foremost about developing and demonstrating research skills . Therefore, the markers want to see that you know which methods to use, can clearly articulate why you’ve chosen then, and know how to deploy them effectively.

Importantly, this chapter requires detail – don’t hold back on the specifics. State exactly what you’ll be doing, with who, when, for how long, etc. Moreover, for every design choice you make, make sure you justify it.

In practice, you will likely end up coming back to this chapter once you’ve undertaken all your data collection and analysis, and revise it based on changes you made during the analysis phase. This is perfectly fine. Its natural for you to add an additional analysis technique, scrap an old one, etc based on where your data lead you. Of course, I’m talking about small changes here – not a fundamental switch from qualitative to quantitative, which will likely send your supervisor in a spin!

You’ve now collected your data and undertaken your analysis, whether qualitative, quantitative or mixed methods. In this chapter, you’ll present the raw results of your analysis . For example, in the case of a quant study, you’ll present the demographic data, descriptive statistics, inferential statistics , etc.

Typically, Chapter 4 is simply a presentation and description of the data, not a discussion of the meaning of the data. In other words, it’s descriptive, rather than analytical – the meaning is discussed in Chapter 5. However, some universities will want you to combine chapters 4 and 5, so that you both present and interpret the meaning of the data at the same time. Check with your institution what their preference is.

Now that you’ve presented the data analysis results, its time to interpret and analyse them. In other words, its time to discuss what they mean, especially in relation to your research question(s).

What you discuss here will depend largely on your chosen methodology. For example, if you’ve gone the quantitative route, you might discuss the relationships between variables . If you’ve gone the qualitative route, you might discuss key themes and the meanings thereof. It all depends on what your research design choices were.

Most importantly, you need to discuss your results in relation to your research questions and aims, as well as the existing literature. What do the results tell you about your research questions? Are they aligned with the existing research or at odds? If so, why might this be? Dig deep into your findings and explain what the findings suggest, in plain English.

The final chapter – you’ve made it! Now that you’ve discussed your interpretation of the results, its time to bring it back to the beginning with the conclusion chapter . In other words, its time to (attempt to) answer your original research question s (from way back in chapter 1). Clearly state what your conclusions are in terms of your research questions. This might feel a bit repetitive, as you would have touched on this in the previous chapter, but its important to bring the discussion full circle and explicitly state your answer(s) to the research question(s).

Next, you’ll typically discuss the implications of your findings . In other words, you’ve answered your research questions – but what does this mean for the real world (or even for academia)? What should now be done differently, given the new insight you’ve generated?

Lastly, you should discuss the limitations of your research, as well as what this means for future research in the area. No study is perfect, especially not a Masters-level. Discuss the shortcomings of your research. Perhaps your methodology was limited, perhaps your sample size was small or not representative, etc, etc. Don’t be afraid to critique your work – the markers want to see that you can identify the limitations of your work. This is a strength, not a weakness. Be brutal!

This marks the end of your core chapters – woohoo! From here on out, it’s pretty smooth sailing.

The reference list is straightforward. It should contain a list of all resources cited in your dissertation, in the required format, e.g. APA , Harvard, etc.

It’s essential that you use reference management software for your dissertation. Do NOT try handle your referencing manually – its far too error prone. On a reference list of multiple pages, you’re going to make mistake. To this end, I suggest considering either Mendeley or Zotero. Both are free and provide a very straightforward interface to ensure that your referencing is 100% on point. I’ve included a simple how-to video for the Mendeley software (my personal favourite) below:

Some universities may ask you to include a bibliography, as opposed to a reference list. These two things are not the same . A bibliography is similar to a reference list, except that it also includes resources which informed your thinking but were not directly cited in your dissertation. So, double-check your brief and make sure you use the right one.

The very last piece of the puzzle is the appendix or set of appendices. This is where you’ll include any supporting data and evidence. Importantly, supporting is the keyword here.

Your appendices should provide additional “nice to know”, depth-adding information, which is not critical to the core analysis. Appendices should not be used as a way to cut down word count (see this post which covers how to reduce word count ). In other words, don’t place content that is critical to the core analysis here, just to save word count. You will not earn marks on any content in the appendices, so don’t try to play the system!

Time to recap…

And there you have it – the traditional dissertation structure and layout, from A-Z. To recap, the core structure for a dissertation or thesis is (typically) as follows:

• Acknowledgments page

Most importantly, the core chapters should reflect the research process (asking, investigating and answering your research question). Moreover, the research question(s) should form the golden thread throughout your dissertation structure. Everything should revolve around the research questions, and as you’ve seen, they should form both the start point (i.e. introduction chapter) and the endpoint (i.e. conclusion chapter).

I hope this post has provided you with clarity about the traditional dissertation/thesis structure and layout. If you have any questions or comments, please leave a comment below, or feel free to get in touch with us. Also, be sure to check out the rest of the  Grad Coach Blog .

Dissertation Chapters: A Guide to Writing Your Dissertation

Embarking on your dissertation is equal parts exhilaration and trepidation. It’s finally your turn to stake out your territory in the body of knowledge and hone your expertise. Naturally, it’s a lot of work, the evidence of which is reflected in your dissertation chapters. These chapters, which comprise the bulk of your dissertation, offer a clear snapshot of your topic, the work that has already been done by other scholars in your field, gaps in the literature, complications, your approach, and more. 

There are many moving parts to a dissertation, and the best way to simplify them is by chapter. Each chapter follows certain rules and serves a specific purpose. The most efficient way to break down the work ahead of you into pieces is to understand the role each chapter plays in the dissertation. 

These are frequently asked questions about dissertation chapters.  

• How many chapters are in a dissertation? 
• What is the content of each dissertation chapter?
• How long is each dissertation chapter? 
• How long does it take to write dissertation chapters?  

How Many Dissertation Chapters are in a Dissertation?

Usually five. While there are no short answers in academia, five dissertation chapters is the convention across many fields, if not most. Five dissertation chapters is a safe bet. As always, though, do your homework and find out exactly what the expectations are for dissertations in your department. 

Read (skim) dissertations written by recent graduates from your department to determine norms for chapter length and the extensiveness of the critical research they did and the studies they conducted. The average could be anything from 130 pages (math) to 500+ pages (history) –either way, you need to know. Also, visit office hours and talk to a few faculty members in your department. Whether they end up on your dissertation committee or not, their perspective will be helpful. 

Content of Each Dissertation Chapter

There is a format for the structure of a dissertation that most fields adhere to, and it is very specific. The first three chapters constitute your dissertation proposal , which must be completed, defended, and approved by your dissertation committee. Once your proposal is successfully defended,  you can proceed with the research you will need to do to write the two final chapters. 

Dissertation Chapters

• Dissertation Chapter One: Introduction to the Study This chapter includes your problem and purpose statements, research questions, and definitions of key terms examined in your research. 
• Dissertation Chapter Two: Literature Review This section is a deep dive of the extant research on your topic, as well as your opportunity to identify and highlight gaps in the literature. 
• Dissertation Chapter Three: Research Methods This chapter offers a summary of how you propose to collect data and your methods of analysis. 
• Dissertation Chapter Four: Results In this section, you present your findings and share the results of your study. 
• Dissertation Chapter Five: Conclusion The final chapter is an opportunity to offer your analysis of your findings and discuss the implications. 

How Long is a Dissertation Chapter?

Dissertation chapter lengths vary, though the number of pages you can expect to write will likely correlate with standard dissertation lengths in your discipline. If you are doing research in a field like anthropology or theology, be prepared to conduct extensive literature reviews and write lengthy chapters. Topics that require a great deal of background information also make the pages add up. 

When thinking about the length of your dissertation chapters, also be aware that chapter lengths are not evenly divided. The bulk of your writing happens in the first three chapters, especially if the literature review covers a lot of ground. If you are writing a 130-page dissertation, the dissertation proposal will take up more than half of that space. Results sections can be comparatively short, and many scholars linger in the conclusion chapter because it’s their time to shine and it’s fun to write. 

How Long Does It Take to Write Dissertation Chapters? 

The amount of time it takes to write a dissertation depends on many factors and can vary greatly depending on the student, the program, and the discipline. This is a great conversation to have with your dissertation advisor, or even the chair of your department if you are still in the early stages of your graduate education. It never hurts to have a rough timeline in mind so you can get organized and plan for the journey ahead. 

These elements often determine the amount of time it takes to write dissertation chapters: 

Academic Discipline

Some graduate degrees take longer than others, and much of that disparity occurs after coursework is completed. In many arts programs, most of the dissertation is written while coursework is taking place. It’s a different story in the sciences and humanities. In fields like biology and chemistry, issues like lab space and institutional approval must be resolved before a study can even begin, much less be written about, and that can take months. In fields like history, the scholarly research phase is similarly extensive. 

University libraries are an academic wonderland, but that doesn’t mean they hold all the answers or everything that you’ll need to get to work on your literature review or background material. Like many burgeoning scholars, I was excited to discover that I would need to travel in order to undertake some archival research for the critical introduction to my dissertation. However, the time required to set this up and visit the sites extended the amount of time it took to write these dissertation chapters. 

Life has a sneaky way of persisting, even when you have a dissertation to write. Many scholars experience unavoidable stops and starts while writing their dissertations, and it’s important to make allowances for being human, even if it interferes with your writing schedule. In my experience, we do our best to write as quickly as possible, but there are inevitable hiccups along the way. No matter. Course correct and keep going. You can do this, and the rewards of having a completed, bound dissertation in your hands will make all the effort worthwhile.

How to Structure a Dissertation – A Step by Step Guide

Published by Owen Ingram at August 11th, 2021 , Revised On September 20, 2023

A dissertation – sometimes called a thesis –  is a long piece of information backed up by extensive research. This one, huge piece of research is what matters the most when students – undergraduates and postgraduates – are in their final year of study.

On the other hand, some institutions, especially in the case of undergraduate students, may or may not require students to write a dissertation. Courses are offered instead. This generally depends on the requirements of that particular institution.

If you are unsure about how to structure your dissertation or thesis, this article will offer you some guidelines to work out what the most important segments of a dissertation paper are and how you should organise them. Why is structure so important in research, anyway?

One way to answer that, as Abbie Hoffman aptly put it, is because: “Structure is more important than content in the transmission of information.”

Also Read:   How to write a dissertation – step by step guide .

How to Structure a Dissertation or Thesis

It should be noted that the exact structure of your dissertation will depend on several factors, such as:

• Your research approach (qualitative/quantitative)
• The nature of your research design (exploratory/descriptive etc.)
• The requirements set for forth by your academic institution.
• The discipline or field your study belongs to. For instance, if you are a humanities student, you will need to develop your dissertation on the same pattern as any long essay .

This will include developing an overall argument to support the thesis statement and organizing chapters around theories or questions. The dissertation will be structured such that it starts with an introduction , develops on the main idea in its main body paragraphs and is then summarised in conclusion .

However, if you are basing your dissertation on primary or empirical research, you will be required to include each of the below components. In most cases of dissertation writing, each of these elements will have to be written as a separate chapter.

But depending on the word count you are provided with and academic subject, you may choose to combine some of these elements.

For example, sciences and engineering students often present results and discussions together in one chapter rather than two different chapters.

If you have any doubts about structuring your dissertation or thesis, it would be a good idea to consult with your academic supervisor and check your department’s requirements.

Parts of  a Dissertation or Thesis

Your dissertation will  start with a t itle page that will contain details of the author/researcher, research topic, degree program (the paper is to be submitted for), and research supervisor. In other words, a title page is the opening page containing all the names and title related to your research.

The name of your university, logo, student ID and submission date can also be presented on the title page. Many academic programs have stringent rules for formatting the dissertation title page.

Acknowledgements

The acknowledgments section allows you to thank those who helped you with your dissertation project. You might want to mention the names of your academic supervisor, family members, friends, God, and participants of your study whose contribution and support enabled you to complete your work.

However, the acknowledgments section is usually optional.

Tip: Many students wrongly assume that they need to thank everyone…even those who had little to no contributions towards the dissertation. This is not the case. You only need to thank those who were directly involved in the research process, such as your participants/volunteers, supervisor(s) etc.

Perhaps the smallest yet important part of a thesis, an abstract contains 5 parts:

• A brief introduction of your research topic.
• The significance of your research.
•  A line or two about the methodology that was used.
• The results and what they mean (briefly); their interpretation(s).
• And lastly, a conclusive comment regarding the results’ interpretation(s) as conclusion .

The abstract is your first chance to impress your readers. So, make sure to get it right. Here are detailed guidelines on how to write abstract for dissertation .

Table of Contents

Table of contents is the section of a dissertation that guides each section of the dissertation paper’s contents. Depending on the level of detail in a table of contents, the most useful headings are listed to provide the reader the page number on which said information may be found at.

Table of contents can be inserted automatically as well as manually using the Microsoft Word Table of Contents feature.

List of Figures and Tables

If your dissertation paper uses several illustrations, tables and figures, you might want to present them in a numbered list in a separate section . Again, this list of tables and figures can be auto-created and auto inserted using the Microsoft Word built-in feature.

List of Abbreviations

Dissertations that include several abbreviations can also have an independent and separate alphabetised  list of abbreviations so readers can easily figure out their meanings.

If you think you have used terms and phrases in your dissertation that readers might not be familiar with, you can create a  glossary  that lists important phrases and terms with their meanings explained.

Introduction

Introduction chapter  briefly introduces the purpose and relevance of your research topic.

Here, you will be expected to list the aim and key objectives of your research so your readers can easily understand what the following chapters of the dissertation will cover. A good dissertation introduction section incorporates the following information:

• It provides background information to give context to your research.
• It clearly specifies the research problem you wish to address with your research. When creating research questions , it is important to make sure your research’s focus and scope are neither too broad nor too narrow.
• it demonstrates how your research is relevant and how it would contribute to the existing knowledge.
• It provides an overview of the structure of your dissertation. The last section of an introduction contains an outline of the following chapters. It could start off with something like: “In the following chapter, past literature has been reviewed and critiqued. The proceeding section lays down major research findings…”
• Theoretical framework – under a separate sub-heading – is also provided within the introductory chapter. Theoretical framework deals with the basic, underlying theory or theories that the research revolves around.

All the information presented under this section should be relevant, clear, and engaging. The readers should be able to figure out the what, why, when, and how of your study once they have read the introduction. Here are comprehensive guidelines on how to structure the introduction to the dissertation .

“Overwhelmed by tight deadlines and tons of assignments to write? There is no need to panic! Our expert academics can help you with every aspect of your dissertation – from topic creation and research problem identification to choosing the methodological approach and data analysis.”

Literature Review 

The  literature review chapter  presents previous research performed on the topic and improves your understanding of the existing literature on your chosen topic. This is usually organised to complement your  primary research  work completed at a later stage.

Make sure that your chosen academic sources are authentic and up-to-date. The literature review chapter must be comprehensive and address the aims and objectives as defined in the introduction chapter. Here is what your literature research chapter should aim to achieve:

• Data collection from authentic and relevant academic sources such as books, journal articles and research papers.
• Analytical assessment of the information collected from those sources; this would involve a critiquing the reviewed researches that is, what their strengths/weaknesses are, why the research method they employed is better than others, importance of their findings, etc.
• Identifying key research gaps, conflicts, patterns, and theories to get your point across to the reader effectively.

While your literature review should summarise previous literature, it is equally important to make sure that you develop a comprehensible argument or structure to justify your research topic. It would help if you considered keeping the following questions in mind when writing the literature review:

• How does your research work fill a certain gap in exiting literature?
• Did you adopt/adapt a new research approach to investigate the topic?
• Does your research solve an unresolved problem?
• Is your research dealing with some groundbreaking topic or theory that others might have overlooked?
• Is your research taking forward an existing theoretical discussion?
• Does your research strengthen and build on current knowledge within your area of study? This is otherwise known as ‘adding to the existing body of knowledge’ in academic circles.

Tip: You might want to establish relationships between variables/concepts to provide descriptive answers to some or all of your research questions. For instance, in case of quantitative research, you might hypothesise that variable A is positively co-related to variable B that is, one increases and so does the other one.

Research Methodology

The methods and techniques ( secondary and/or primar y) employed to collect research data are discussed in detail in the  Methodology chapter. The most commonly used primary data collection methods are:

• questionnaires
• focus groups
• observations

Essentially, the methodology chapter allows the researcher to explain how he/she achieved the findings, why they are reliable and how they helped him/her test the research hypotheses or address the research problem.

You might want to consider the following when writing methodology for the dissertation:

• Type of research and approach your work is based on. Some of the most widely used types of research include experimental, quantitative and qualitative methodologies.
• Data collection techniques that were employed such as questionnaires, surveys, focus groups, observations etc.
• Details of how, when, where, and what of the research that was conducted.
• Data analysis strategies employed (for instance, regression analysis).
• Software and tools used for data analysis (Excel, STATA, SPSS, lab equipment, etc.).
• Research limitations to highlight any hurdles you had to overcome when carrying our research. Limitations might or might not be mentioned within research methodology. Some institutions’ guidelines dictate they be mentioned under a separate section alongside recommendations.
• Justification of your selection of research approach and research methodology.

Here is a comprehensive article on  how to structure a dissertation methodology .

Research Findings

In this section, you present your research findings. The dissertation findings chapter  is built around the research questions, as outlined in the introduction chapter. Report findings that are directly relevant to your research questions.

Any information that is not directly relevant to research questions or hypotheses but could be useful for the readers can be placed under the  Appendices .

As indicated above, you can either develop a  standalone chapter  to present your findings or combine them with the discussion chapter. This choice depends on  the type of research involved and the academic subject, as well as what your institution’s academic guidelines dictate.

For example, it is common to have both findings and discussion grouped under the same section, particularly if the dissertation is based on qualitative research data.

On the other hand, dissertations that use quantitative or experimental data should present findings and analysis/discussion in two separate chapters. Here are some sample dissertations to help you figure out the best structure for your own project.

Sample Dissertation

Tip: Try to present as many charts, graphs, illustrations and tables in the findings chapter to improve your data presentation. Provide their qualitative interpretations alongside, too. Refrain from explaining the information that is already evident from figures and tables.

The findings are followed by the  Discussion chapter , which is considered the heart of any dissertation paper. The discussion section is an opportunity for you to tie the knots together to address the research questions and present arguments, models and key themes.

This chapter can make or break your research.

The discussion chapter does not require any new data or information because it is more about the interpretation(s) of the data you have already collected and presented. Here are some questions for you to think over when writing the discussion chapter:

• Did your work answer all the research questions or tested the hypothesis?
• Did you come up with some unexpected results for which you have to provide an additional explanation or justification?
• Are there any limitations that could have influenced your research findings?

Here is an article on how to  structure a dissertation discussion .

Conclusions corresponding to each research objective are provided in the  Conclusion section . This is usually done by revisiting the research questions to finally close the dissertation. Some institutions may specifically ask for recommendations to evaluate your critical thinking.

By the end, the readers should have a clear apprehension of your fundamental case with a focus on  what methods of research were employed  and what you achieved from this research.

Quick Question: Does the conclusion chapter reflect on the contributions your research work will make to existing knowledge?

Answer: Yes, the conclusion chapter of the research paper typically includes a reflection on the research’s contributions to existing knowledge.  In the “conclusion chapter”, you have to summarise the key findings and discuss how they add value to the existing literature on the current topic.

Reference list

All academic sources that you collected information from should be cited in-text and also presented in a  reference list (or a bibliography in case you include references that you read for the research but didn’t end up citing in the text), so the readers can easily locate the source of information when/if needed.

At most UK universities, Harvard referencing is the recommended style of referencing. It has strict and specific requirements on how to format a reference resource. Other common styles of referencing include MLA, APA, Footnotes, etc.

Each chapter of the dissertation should have relevant information. Any information that is not directly relevant to your research topic but your readers might be interested in (interview transcripts etc.) should be moved under the Appendices section .

Things like questionnaires, survey items or readings that were used in the study’s experiment are mostly included under appendices.

FAQs About Structure a Dissertation

What does the title page of a dissertation contain.

The title page will contain details of the author/researcher, research topic , degree program (the paper is to be submitted for) and research supervisor’s name(s). The name of your university, logo, student number and submission date can also be presented on the title page.

What is the purpose of adding acknowledgement?

The acknowledgements section allows you to thank those who helped you with your dissertation project. You might want to mention the names of your academic supervisor, family members, friends, God and participants of your study whose contribution and support enabled you to complete your work.

Can I omit the glossary from the dissertation?

Yes, but only if you think that your paper does not contain any terms or phrases that the reader might not understand. If you think you have used them in the paper,  you must create a glossary that lists important phrases and terms with their meanings explained.

What is the purpose of appendices in a dissertation?

Any information that is not directly relevant to research questions or hypotheses but could be useful for the readers can be placed under the Appendices, such as questionnaire that was used in the study.

Which referencing style should I use in my dissertation?

You can use any of the referencing styles such as APA, MLA, and Harvard, according to the recommendation of your university; however, almost all UK institutions prefer Harvard referencing style .

What is the difference between references and bibliography?

References contain all the works that you read up and used and therefore, cited within the text of your thesis. However, in case you read on some works and resources that you didn’t end up citing in-text, they will be referenced in what is called a bibliography.

Additional readings might also be present alongside each bibliography entry for readers.

Writing a Methodology Chapter

What is a dissertation methodology.

• Structuring your methodology
• Dos and don’ts

A well-written methodology chapter is essential in establishing the credibility and validity of your research, as it allows other researchers to reproduce your study and build upon your findings . In this guide, we will provide you with step-by-step instructions on how to write a comprehensive and well-organized methodology chapter that will effectively communicate the methodology you used in your research. 

• The methodology explains your methodological approach and explains what you did and how , and why .
• The methodology section allows the reader to critically evaluate a study's overall credibility . 
• The purpose is to give another researcher enough information to replicate the study and obtain similar results.
• Methods and methodology are not synonyms (overarching approach vs  specific tools and procedures used to collect and analyse data).

The methodology chapter, as any other chapters of your dissertation except the introduction and conclusion chapters, consists of 3 main sections: introduction, main body and conclusion/summary.

[Adapted from: Succeeding with your Master’s Dissertation: A step-by-step handbook ]

The sections included in the main body depend on the type of research and the type of dissertation. For example:

• In the traditional dissertation , it is commonly a separate chapter preceding the Results chapter.
• In topic-based dissertations , the Methodology chapter might have a different title such as ‘Conducting Research’.
• In experiment-based or dissertations by compilation , each study or experiment might contain its own methodology or methods section. 

Step 1: Explain your research design/approach

This commonly includes a restatement of the research aim(s) , a justification of choice of research methods , overview of specific method(s) used .

Step 2: Explain your methods of data collection

This involves explaining how the research was conducted and how the data were obtained . It requires a detailed description of processes and procedures and a justification of the reasons for doing so . This might include describing:

• How was the data collection tool designed
• How participants were obtained and how was the sample drawn
• The location in which the data collection took place
• The themes covered during the data collection or any variables and measures
• Any piloting, adjustments made and reasons behind those
• Ethical considerations and any obstacles faced and how those were addressed

Step 3: Explain your methods of data analysis

This involves explaining how you processed and analysed the data. However, do not start discussing the results unless you are combining results and discussion into one chapter (commonly seen in qualitative research). For example, you might want to include:

• How you prepared the data before analysis (e.g., checking for missing data, removing outliers)
• The software used to analyse the data (e.g., SPSS, Atlas.ti)
• The methods used to analyse the data (e.g., regression analysis, thematic analysis)

For more information on language used in methodology chapters have a look at our page  Language used in dissertations . 

Writing a Results Chapter

• What is a results chapter?
• Structuring your results
• Presenting your results
• Using tables & figures

The results chapter is a crucial section of any piece of research, as it presents and interprets the findings obtained from the study. This chapter allows you to communicate the outcomes of your investigation, analyse the data, and draw meaningful conclusions . Crafting an effective results chapter requires careful planning, organization, and attention to detail. This guide aims to provide you with a step-by-step approach to writing a results chapter that effectively communicates your research findings.

• The results section of your dissertation is where you report the findings of your study based upon the information gathered as a result of the methodology you applied.
• The results section should simply state the findings , without bias or interpretation, and arranged in a logical sequence . 
• The results section should always be written in the past tense . 
• The page length of this section is set by the amount and types of data to be reported. Try to be concise and use non-textual elements .
• Avoid providing data that is not critical to answering the research question(s). 

The results chapter, as any other chapters of your dissertation except the introduction and conclusion chapters, consists of 3 main sections: introduction, main body and conclusion/summary.

Introduction

This might include:

• A brief reminder of the methodological approach or methods.
• A preview of the chapter: outline the organisation and state the scope (What is included? How is the chapter organised?)

The order of results can vary.  Some suggestions are:

• From most important to least important.
• As a logical response to the research questions or problems you are trying to answer or solve.  
• If you are using a range of methods or a number of experimental elements , group the method/procedure together with the relevant results. 
• In quantitative research , the descriptive statistics are generally presented first, then the results of each of the hypotheses or research questions that were tested.
• The information in the results section should be organised to show how the data tests the research questions or hypotheses , and should be presented sequentially to respond to each research question or hypothesis.

Conclusion or Chapter Summary

• A brief summary of the key results.
• Signpost how these will be discussed in the following chapter (leads to your discussion chapter).

Describe the findings of the study, but do not start to interpret the results . This will take place in the discussion section, which comes next, unless you decide to combine results and discussion, which is common in qualitative research.

Presenting Qualitative Results

• Structure your results around key themes .
• For each theme, make general observations about what the data showed.
• Support these points with direct quotations .
• If possible, include a brief conclusion (‘so what?’) to the observation and highlight any links with other findings.
• Repeat this process as many times as necessary.
• Further information can be included in an appendix .

Presenting Quantitative Results

• Structure your results around your research sub-questions .
• For each sub-question, present the relevant results , including any statistical analysis you conducted, and briefly evaluate their significance. 
• Highlight the most important trends , differences, and relationships among the data, but do not speculate on their meaning or consequences.
• If you have results that are not directly relevant to answering your questions, or any extra information that will help the reader understand how you gathered the data, you can include them in an appendix .

The description of tables and figures in academic written texts commonly includes two different elements:

• Location or summary statement: identifies the table or figure and indicates its content.
• Highlighting statement or statements: point out and describe the relevant or significant data.

Dos and don'ts of using tables and figures

For more information on the language used in results chapters see the Language section of this guide.

You can use the checklist below to ensure your results chapter includes all relevant information:

Writing a Discussion Chapter

What is a discussion chapter.

• Structuring your discussion
• Dos and don'ts

The discussion chapter of a dissertation is an essential component that showcases your ability to analyse and interpret your research findings, draw meaningful conclusions, and provide valuable insights into the broader academic and practical implications of your study. This guide aims to provide you with a comprehensive overview of how to write a compelling and well-structured discussion chapter that strengthens the overall impact of your dissertation.

• Explains what the results mean;
• Interprets and discusses the data;
• Compares it with other research (literature review);
• Evaluates its importance;
• Points out the limitations of your research;
• Raises questions for future directions .

Tip: When writing your discussion chapter, you might want to revisit your literature review chapter and ensure that the relevant literature included in this chapter has been already presented in the Literature Review.

The discussion chapter, as any other chapters of your dissertation except the introduction and conclusion chapters, consists of 3 main sections: introduction, main body and conclusion/summary.

[Adapted from: Succeeding with your Master’s Dissertation: A step-by-step handbook ]  

Your discussion should focus on explaining and evaluating your findings, displaying their connection to the previous literature (i.e., your literature review ) and research questions , as well as presenting a persuasive argument to support your overall conclusion.  While there are many different ways to write this section, you can focus your discussion around three key aspects:

• Interpretations: What is the meaning behind the results?
• Implications: Why do the results matter? Why are the results relevant?
• Limitations: What can’t the results tell us? What are the constraints or limitations of the results in terms of what they can reveal?

This can be done following the 5 steps below:  

Step 1: Summarise your findings

You can begin this section by reiterating your research problem and providing a succinct overview of your main findings. Do not just repeat all the data that you have already reported in the previous chapter, instead present a clear statement that directly addresses your research questions.

Step 2: Interpret your findings

While the significance of your results may appear apparent to you, it is crucial to explicitly articulate their importance for your reader by demonstrating how they directly address your research question. The manner in which you interpret the data will vary depending on the type of research conducted. However, some common approaches to interpreting the data include:

• Recognizing correlations, patterns, and relationships within the data
• Analysing whether the results align with your expectations or support your hypotheses
• Placing your findings within the context of prior research and established theories
• Elucidating unexpected results and assessing their significance
• Considering alternative explanations and presenting a compelling argument in favour of your position.

Step 3: Place your findings in context (literature review)

A helpful way to place your findings within context and identifying how your findings agree or disagree with the previous literature is to use a summary table such as the one below:

This can result in a paragraph like: The importance of timely feedback in block has also been stressed by students and faculty as one of the reasons as to why single assessments at the end of the module, and more specifically exams, are the least accurate method in block delivery. Although exams were considered by some participants as necessary in certain disciplines, participants agreed that this assessment type does not show knowledge depth as indicated by Dang et al. (2022) and students might receive limited or no feedback as highlighted by Race (2015). Therefore, incorporating frequent and a variety of assessments with timely feedback into block delivery could enhance student learning outcomes and improve the accuracy of assessments.

Step 4: Acknowledge the limitations

Every piece of research has limitations and acknowledging these is crucial for establishing the credibility of the study. The purpose of discussing these limitations is not to highlight errors, but rather to provide an accurate understanding of the conclusions that can and cannot be drawn from the study, as well as to highlight further areas for research on the topic. Limitations might relate to your research design, methodological choices, or unforeseen challenges encountered during the research process. Here are some examples:

• If the sample size was small or limited to a specific group of individuals, it is necessary to explain how the generalizability of the findings is constrained.
• If difficulties were encountered during data collection or analysis, it is important to elucidate how these challenges might have impacted the results.
• If there are potential confounding variables that could not be controlled, it is essential to acknowledge the potential effects they might have had.

How to write a PhD thesis: a step-by-step guide

A draft isn’t a perfect, finished product; it is your opportunity to start getting words down on paper, writes Kelly Louise Preece

Formative, summative or diagnostic assessment a guide, emotions and learning: what role do emotions play in how and why students learn, how to assess and enhance students’ ai literacy, how hard can it be testing ai detection tools.

Congratulations; you’ve finished your research! Time to write your PhD thesis. This resource will take you through an eight-step plan for drafting your chapters and your thesis as a whole. 

Organise your material

Before you start, it’s important to get organised. Take a step back and look at the data you have, then reorganise your research. Which parts of it are central to your thesis and which bits need putting to one side? Label and organise everything using logical folders – make it easy for yourself! Academic and blogger Pat Thomson calls this  “Clean up to get clearer” . Thomson suggests these questions to ask yourself before you start writing:

• What data do you have? You might find it useful to write out a list of types of data (your supervisor will find this list useful too.) This list is also an audit document that can go in your thesis. Do you have any for the “cutting room floor”? Take a deep breath and put it in a separate non-thesis file. You can easily retrieve it if it turns out you need it.
• What do you have already written? What chunks of material have you written so far that could form the basis of pieces of the thesis text? They will most likely need to be revised but they are useful starting points. Do you have any holding text? That is material you already know has to be rewritten but contains information that will be the basis of a new piece of text.
• What have you read and what do you still need to read? Are there new texts that you need to consult now after your analysis? What readings can you now put to one side, knowing that they aren’t useful for this thesis – although they might be useful at another time?
• What goes with what? Can you create chunks or themes of materials that are going to form the basis of some chunks of your text, perhaps even chapters?

Once you have assessed and sorted what you have collected and generated you will be in much better shape to approach the big task of composing the dissertation. 

Decide on a key message

A key message is a summary of new information communicated in your thesis. You should have started to map this out already in the section on argument and contribution – an overarching argument with building blocks that you will flesh out in individual chapters.

You have already mapped your argument visually, now you need to begin writing it in prose. Following another of Pat Thomson’s exercises, write a “tiny text” thesis abstract. This doesn’t have to be elegant, or indeed the finished product, but it will help you articulate the argument you want your thesis to make. You create a tiny text using a five-paragraph structure:

• The first sentence addresses the broad context. This locates the study in a policy, practice or research field.
• The second sentence establishes a problem related to the broad context you have set out. It often starts with “But”, “Yet” or “However”.
• The third sentence says what specific research has been done. This often starts with “This research” or “I report…”
• The fourth sentence reports the results. Don’t try to be too tricky here, just start with something like: “This study shows,” or “Analysis of the data suggests that…”
• The fifth and final sentence addresses the “So What?” question and makes clear the claim to contribution.

Here’s an example that Thomson provides:

Secondary school arts are in trouble, as the fall in enrolments in arts subjects dramatically attests. However, there is patchy evidence about the benefits of studying arts subjects at school and this makes it hard to argue why the drop in arts enrolments matters. This thesis reports on research which attempts to provide some answers to this problem – a longitudinal study which followed two groups of senior secondary students, one group enrolled in arts subjects and the other not, for three years. The results of the study demonstrate the benefits of young people’s engagement in arts activities, both in and out of school, as well as the connections between the two. The study not only adds to what is known about the benefits of both formal and informal arts education but also provides robust evidence for policymakers and practitioners arguing for the benefits of the arts. You can  find out more about tiny texts and thesis abstracts on Thomson’s blog.

Write a plan

You might not be a planner when it comes to writing. You might prefer to sit, type and think through ideas as you go. That’s OK. Everybody works differently. But one of the benefits of planning your writing is that your plan can help you when you get stuck. It can help with writer’s block (more on this shortly!) but also maintain clarity of intention and purpose in your writing.

You can do this by creating a  thesis skeleton or storyboard , planning the order of your chapters, thinking of potential titles (which may change at a later stage), noting down what each chapter/section will cover and considering how many words you will dedicate to each chapter (make sure the total doesn’t exceed the maximum word limit allowed).

Use your plan to help prompt your writing when you get stuck and to develop clarity in your writing.

Some starting points include:

• This chapter will argue that…
• This section illustrates that…
• This paragraph provides evidence that…

Of course, we wish it werethat easy. But you need to approach your first draft as exactly that: a draft. It isn’t a perfect, finished product; it is your opportunity to start getting words down on paper. Start with whichever chapter you feel you want to write first; you don’t necessarily have to write the introduction first. Depending on your research, you may find it easier to begin with your empirical/data chapters.

Vitae advocates for the “three draft approach” to help with this and to stop you from focusing on finding exactly the right word or transition as part of your first draft.

What Is a Dissertation? | 5 Essential Questions to Get Started

Published on 26 March 2020 by Jack Caulfield . Revised on 5 May 2022.

A dissertation is a large research project undertaken at the end of a degree. It involves in-depth consideration of a problem or question chosen by the student. It is usually the largest (and final) piece of written work produced during a degree.

The length and structure of a dissertation vary widely depending on the level and field of study. However, there are some key questions that can help you understand the requirements and get started on your dissertation project.

Table of contents

When and why do you have to write a dissertation, who will supervise your dissertation, what type of research will you do, how should your dissertation be structured, what formatting and referencing rules do you have to follow, frequently asked questions about dissertations.

A dissertation, sometimes called a thesis, comes at the end of an undergraduate or postgraduate degree. It is a larger project than the other essays you’ve written, requiring a higher word count and a greater depth of research.

You’ll generally work on your dissertation during the final year of your degree, over a longer period than you would take for a standard essay . For example, the dissertation might be your main focus for the last six months of your degree.

Why is the dissertation important?

The dissertation is a test of your capacity for independent research. You are given a lot of autonomy in writing your dissertation: you come up with your own ideas, conduct your own research, and write and structure the text by yourself.

This means that it is an important preparation for your future, whether you continue in academia or not: it teaches you to manage your own time, generate original ideas, and work independently.

The only proofreading tool specialized in correcting academic writing

The academic proofreading tool has been trained on 1000s of academic texts and by native English editors. Making it the most accurate and reliable proofreading tool for students.

Correct my document today

During the planning and writing of your dissertation, you’ll work with a supervisor from your department. The supervisor’s job is to give you feedback and advice throughout the process.

The dissertation supervisor is often assigned by the department, but you might be allowed to indicate preferences or approach potential supervisors. If so, try to pick someone who is familiar with your chosen topic, whom you get along with on a personal level, and whose feedback you’ve found useful in the past.

How will your supervisor help you?

Your supervisor is there to guide you through the dissertation project, but you’re still working independently. They can give feedback on your ideas, but not come up with ideas for you.

You may need to take the initiative to request an initial meeting with your supervisor. Then you can plan out your future meetings and set reasonable deadlines for things like completion of data collection, a structure outline, a first chapter, a first draft, and so on.

Make sure to prepare in advance for your meetings. Formulate your ideas as fully as you can, and determine where exactly you’re having difficulties so you can ask your supervisor for specific advice.

Your approach to your dissertation will vary depending on your field of study. The first thing to consider is whether you will do empirical research , which involves collecting original data, or non-empirical research , which involves analysing sources.

Empirical dissertations (sciences)

An empirical dissertation focuses on collecting and analysing original data. You’ll usually write this type of dissertation if you are studying a subject in the sciences or social sciences.

• What are airline workers’ attitudes towards the challenges posed for their industry by climate change?
• How effective is cognitive behavioural therapy in treating depression in young adults?
• What are the short-term health effects of switching from smoking cigarettes to e-cigarettes?

There are many different empirical research methods you can use to answer these questions – for example, experiments , observations, surveys , and interviews.

When doing empirical research, you need to consider things like the variables you will investigate, the reliability and validity of your measurements, and your sampling method . The aim is to produce robust, reproducible scientific knowledge.

Non-empirical dissertations (arts and humanities)

A non-empirical dissertation works with existing research or other texts, presenting original analysis, critique and argumentation, but no original data. This approach is typical of arts and humanities subjects.

• What attitudes did commentators in the British press take towards the French Revolution in 1789–1792?
• How do the themes of gender and inheritance intersect in Shakespeare’s Macbeth ?
• How did Plato’s Republic and Thomas More’s Utopia influence nineteenth century utopian socialist thought?

The first steps in this type of dissertation are to decide on your topic and begin collecting your primary and secondary sources .

Primary sources are the direct objects of your research. They give you first-hand evidence about your subject. Examples of primary sources include novels, artworks and historical documents.

Secondary sources provide information that informs your analysis. They describe, interpret, or evaluate information from primary sources. For example, you might consider previous analyses of the novel or author you are working on, or theoretical texts that you plan to apply to your primary sources.

Dissertations are divided into chapters and sections. Empirical dissertations usually follow a standard structure, while non-empirical dissertations are more flexible.

Structure of an empirical dissertation

Empirical dissertations generally include these chapters:

• Introduction : An explanation of your topic and the research question(s) you want to answer.
• Literature review : A survey and evaluation of previous research on your topic.
• Methodology : An explanation of how you collected and analysed your data.
• Results : A brief description of what you found.
• Discussion : Interpretation of what these results reveal.
• Conclusion : Answers to your research question(s) and summary of what your findings contribute to knowledge in your field.

Sometimes the order or naming of chapters might be slightly different, but all of the above information must be included in order to produce thorough, valid scientific research.

Other dissertation structures

If your dissertation doesn’t involve data collection, your structure is more flexible. You can think of it like an extended essay – the text should be logically organised in a way that serves your argument:

• Introduction: An explanation of your topic and the question(s) you want to answer.
• Main body: The development of your analysis, usually divided into 2–4 chapters.
• Conclusion: Answers to your research question(s) and summary of what your analysis contributes to knowledge in your field.

The chapters of the main body can be organised around different themes, time periods, or texts. Below you can see some example structures for dissertations in different subjects.

• Political philosophy

This example, on the topic of the British press’s coverage of the French Revolution, shows how you might structure each chapter around a specific theme.

This example, on the topic of Plato’s and More’s influences on utopian socialist thought, shows a different approach to dividing the chapters by theme.

This example, a master’s dissertation on the topic of how writers respond to persecution, shows how you can also use section headings within each chapter. Each of the three chapters deals with a specific text, while the sections are organised thematically.

Prevent plagiarism, run a free check.

Like other academic texts, it’s important that your dissertation follows the formatting guidelines set out by your university. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

Formatting guidelines concern things like:

• line spacing
• page numbers
• punctuation
• title pages
• presentation of tables and figures

If you’re unsure about the formatting requirements, check with your supervisor or department. You can lose marks unnecessarily over mistakes, so it’s worth taking the time to get all these elements right.

How will you reference your sources?

Referencing means properly listing the sources you cite and refer to in your dissertation, so that the reader can find them. This avoids plagiarism by acknowledging where you’ve used the work of others.

Keep track of everything you read as you prepare your dissertation. The key information to note down for a reference is:

• The publication date
• Page numbers for the parts you refer to (especially when using direct quotes)

Different referencing styles each have their own specific rules for how to reference. The most commonly used styles in UK universities are listed below.

The words ‘ dissertation ’ and ‘thesis’ both refer to a large written research project undertaken to complete a degree, but they are used differently depending on the country:

• In the UK, you write a dissertation at the end of a bachelor’s or master’s degree, and you write a thesis to complete a PhD.
• In the US, it’s the other way around: you may write a thesis at the end of a bachelor’s or master’s degree, and you write a dissertation to complete a PhD.

The main difference is in terms of scale – a dissertation is usually much longer than the other essays you complete during your degree.

Another key difference is that you are given much more independence when working on a dissertation. You choose your own dissertation topic , and you have to conduct the research and write the dissertation yourself (with some assistance from your supervisor).

Dissertation word counts vary widely across different fields, institutions, and levels of education:

• An undergraduate dissertation is typically 8,000–15,000 words
• A master’s dissertation is typically 12,000–50,000 words
• A PhD thesis is typically book-length: 70,000–100,000 words

However, none of these are strict guidelines – your word count may be lower or higher than the numbers stated here. Always check the guidelines provided by your university to determine how long your own dissertation should be.

At the bachelor’s and master’s levels, the dissertation is usually the main focus of your final year. You might work on it (alongside other classes) for the entirety of the final year, or for the last six months. This includes formulating an idea, doing the research, and writing up.

A PhD thesis takes a longer time, as the thesis is the main focus of the degree. A PhD thesis might be being formulated and worked on for the whole four years of the degree program. The writing process alone can take around 18 months.

Dissertation Methodology

In any research, the methodology chapter is one of the key components of your dissertation. It provides a detailed description of the methods you used to conduct your research and helps readers understand how you obtained your data and how you plan to analyze it. This section is crucial for replicating the study and validating its results.

Here are the basic elements that are typically included in a dissertation methodology:

• Introduction : This section should explain the importance and goals of your research .
• Research Design : Outline your research approach and why it’s appropriate for your study. You might be conducting an experimental research, a qualitative research, a quantitative research, or a mixed-methods research.
• Data Collection : This section should detail the methods you used to collect your data. Did you use surveys, interviews, observations, etc.? Why did you choose these methods? You should also include who your participants were, how you recruited them, and any ethical considerations.
• Data Analysis : Explain how you intend to analyze the data you collected. This could include statistical analysis, thematic analysis, content analysis, etc., depending on the nature of your study.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your study. For instance, you could discuss measures taken to reduce bias, how you ensured that your measures accurately capture what they were intended to, or how you will handle any limitations in your study.
• Ethical Considerations : This is where you state how you have considered ethical issues related to your research, how you have protected the participants’ rights, and how you have complied with the relevant ethical guidelines.
• Limitations : Acknowledge any limitations of your methodology, including any biases and constraints that might have affected your study.
• Summary : Recap the key points of your methodology chapter, highlighting the overall approach and rationalization of your research.

Types of Dissertation Methodology

The type of methodology you choose for your dissertation will depend on the nature of your research question and the field you’re working in. Here are some of the most common types of methodologies used in dissertations:

Experimental Research

This involves creating an experiment that will test your hypothesis. You’ll need to design an experiment, manipulate variables, collect data, and analyze that data to draw conclusions. This is commonly used in fields like psychology, biology, and physics.

Survey Research

This type of research involves gathering data from a large number of participants using tools like questionnaires or surveys. It can be used to collect a large amount of data and is often used in fields like sociology, marketing, and public health.

Qualitative Research

This type of research is used to explore complex phenomena that can’t be easily quantified. Methods include interviews, focus groups, and observations. This methodology is common in fields like anthropology, sociology, and education.

Quantitative Research

Quantitative research uses numerical data to answer research questions. This can include statistical, mathematical, or computational techniques. It’s common in fields like economics, psychology, and health sciences.

Case Study Research

This type of research involves in-depth investigation of a particular case, such as an individual, group, or event. This methodology is often used in psychology, social sciences, and business.

Mixed Methods Research

This combines qualitative and quantitative research methods in a single study. It’s used to answer more complex research questions and is becoming more popular in fields like social sciences, health sciences, and education.

Action Research

This type of research involves taking action and then reflecting upon the results. This cycle of action-reflection-action continues throughout the study. It’s often used in fields like education and organizational development.

Longitudinal Research

This type of research involves studying the same group of individuals over an extended period of time. This could involve surveys, observations, or experiments. It’s common in fields like psychology, sociology, and medicine.

Ethnographic Research

This type of research involves the in-depth study of people and cultures. Researchers immerse themselves in the culture they’re studying to collect data. This is often used in fields like anthropology and social sciences.

Structure of Dissertation Methodology

The structure of a dissertation methodology can vary depending on your field of study, the nature of your research, and the guidelines of your institution. However, a standard structure typically includes the following elements:

• Introduction : Briefly introduce your overall approach to the research. Explain what you plan to explore and why it’s important.
• Research Design/Approach : Describe your overall research design. This can be qualitative, quantitative, or mixed methods. Explain the rationale behind your chosen design and why it is suitable for your research questions or hypotheses.
• Data Collection Methods : Detail the methods you used to collect your data. You should include what type of data you collected, how you collected it, and why you chose this method. If relevant, you can also include information about your sample population, such as how many people participated, how they were chosen, and any relevant demographic information.
• Data Analysis Methods : Explain how you plan to analyze your collected data. This will depend on the nature of your data. For example, if you collected quantitative data, you might discuss statistical analysis techniques. If you collected qualitative data, you might discuss coding strategies, thematic analysis, or narrative analysis.
• Reliability and Validity : Discuss how you’ve ensured the reliability and validity of your research. This might include steps you took to reduce bias or increase the accuracy of your measurements.
• Ethical Considerations : If relevant, discuss any ethical issues associated with your research. This might include how you obtained informed consent from participants, how you ensured participants’ privacy and confidentiality, or any potential conflicts of interest.

Example of Dissertation Methodology

An Example of Dissertation Methodology is as follows:

Chapter 3: Methodology

• Introduction

This chapter details the methodology adopted in this research. The study aimed to explore the relationship between stress and productivity in the workplace. A mixed-methods research design was used to collect and analyze data.

Research Design

This study adopted a mixed-methods approach, combining quantitative surveys with qualitative interviews to provide a comprehensive understanding of the research problem. The rationale for this approach is that while quantitative data can provide a broad overview of the relationships between variables, qualitative data can provide deeper insights into the nuances of these relationships.

Data Collection Methods

Quantitative Data Collection : An online self-report questionnaire was used to collect data from participants. The questionnaire consisted of two standardized scales: the Perceived Stress Scale (PSS) to measure stress levels and the Individual Work Productivity Questionnaire (IWPQ) to measure productivity. The sample consisted of 200 office workers randomly selected from various companies in the city.

Qualitative Data Collection : Semi-structured interviews were conducted with 20 participants chosen from the initial sample. The interview guide included questions about participants’ experiences with stress and how they perceived its impact on their productivity.

Data Analysis Methods

Quantitative Data Analysis : Descriptive and inferential statistics were used to analyze the survey data. Pearson’s correlation was used to examine the relationship between stress and productivity.

Qualitative Data Analysis : Interviews were transcribed and subjected to thematic analysis using NVivo software. This process allowed for identifying and analyzing patterns and themes regarding the impact of stress on productivity.

Reliability and Validity

To ensure reliability and validity, standardized measures with good psychometric properties were used. In qualitative data analysis, triangulation was employed by having two researchers independently analyze the data and then compare findings.

Ethical Considerations

All participants provided informed consent prior to their involvement in the study. They were informed about the purpose of the study, their rights as participants, and the confidentiality of their responses.

Limitations

The main limitation of this study is its reliance on self-report measures, which can be subject to biases such as social desirability bias. Moreover, the sample was drawn from a single city, which may limit the generalizability of the findings.

Where to Write Dissertation Methodology

In a dissertation or thesis, the Methodology section usually follows the Literature Review. This placement allows the Methodology to build upon the theoretical framework and existing research outlined in the Literature Review, and precedes the Results or Findings section. Here’s a basic outline of how most dissertations are structured:

• Acknowledgements
• Literature Review (or it may be interspersed throughout the dissertation)
• Methodology
• Results/Findings
• References/Bibliography

In the Methodology chapter, you will discuss the research design, data collection methods, data analysis methods, and any ethical considerations pertaining to your study. This allows your readers to understand how your research was conducted and how you arrived at your results.

Advantages of Dissertation Methodology

The dissertation methodology section plays an important role in a dissertation for several reasons. Here are some of the advantages of having a well-crafted methodology section in your dissertation:

• Clarifies Your Research Approach : The methodology section explains how you plan to tackle your research question, providing a clear plan for data collection and analysis.
• Enables Replication : A detailed methodology allows other researchers to replicate your study. Replication is an important aspect of scientific research because it provides validation of the study’s results.
• Demonstrates Rigor : A well-written methodology shows that you’ve thought critically about your research methods and have chosen the most appropriate ones for your research question. This adds credibility to your study.
• Enhances Transparency : Detailing your methods allows readers to understand the steps you took in your research. This increases the transparency of your study and allows readers to evaluate potential biases or limitations.
• Helps in Addressing Research Limitations : In your methodology section, you can acknowledge and explain the limitations of your research. This is important as it shows you understand that no research method is perfect and there are always potential weaknesses.
• Facilitates Peer Review : A detailed methodology helps peer reviewers assess the soundness of your research design. This is an important part of the publication process if you aim to publish your dissertation in a peer-reviewed journal.
• Establishes the Validity and Reliability : Your methodology section should also include a discussion of the steps you took to ensure the validity and reliability of your measurements, which is crucial for establishing the overall quality of your research.

MULTIPLE PATHWAYS TO SUPRATHRESHOLD SPEECH IN NOISE DEFICIT IN HUMAN LISTENERS

Threshold audiometry, which measures the audibility of sounds in quiet, is currently the foundation of clinical hearing evaluation and patient management. Yet, despite using clinically prescribed state-of-the-art hearing aids that can restore audibility in quiet, patients with sensorineural hearing loss (SNHL) experience difficulty understanding speech in noisy backgrounds (e.g. cocktail party-like situations). This is likely because the amplification provided by modern hearing aids while restoring audibility in quiet, cannot compensate for the degradation in neural coding of speech in noise resulting from a range of non-linear changes in cochlear function that occur due to hearing damage. Furthermore, in addition to robust neural coding, the efficacy of cognitive processes such as selective attention also influences speech understanding outcomes. While much is known about how audibility affects speech understanding outcomes, little is known about suprathreshold deficits in SNHL. Unfortunately, direct measurements of the physiological changes in human inner ears are not possible due to ethical constraints. Here, I use noninvasive tools to characterize the effects of two less-familiar forms of SNHL: cochlear synaptopathy (CS; chapter 2) and distorted tonotopy (DT; chapters 3 and 4). Results from our experiments in Chapter 2 showed that age-related CS degrades envelope coding even in the absence of audiometric hearing loss and that these effects can be quantified using non-invasive electroencephalography (EEG)-based envelope-following response (EFRs) metrics. To date, DT has been only studied in laboratory-controlled animal models. In chapters 3 and 4, I combined psychophysical tuning curves, EFRs, and speech-in-noise measurements to characterize the effects of DT. Our results suggest that low-frequency noise produces a strong masking effect on the coding of speech in individuals with SNHL and that an index of DT (tip-to-tail ratio) obtained from psychophysical tuning curves can account for a significant portion of the large individual variability in listening outcomes among hearing-aid users, over and beyond audibility. Lastly, I propose a machine-learning framework to study the effect of attentional control on speech-in-noise outcomes (chapter 5). Specifically, I introduced a machine-learning model to assess how attentional control influences speech-in-noise understanding, using EEG to predict listening performance outcomes based on prestimulus neural activity. This design allows for examining the influence of top-down executive function on listening outcomes separately from the peripheral effects of SNHL. The results from our study suggest prestimulus EEG can predict subsequent listening outcomes and the changes in alpha rhythm may be used as a neural correlate of attention.
