What Is a Thesis? | Ultimate Guide & Examples
A thesis is a type of research paper based on your original research. It is usually submitted as the final step of a PhD program in the UK.
Writing a thesis can be a daunting experience. Indeed, alongside a dissertation, it is the longest piece of writing students typically complete. It relies on your ability to conduct research from start to finish: designing your research, collecting data, developing a robust analysis, drawing strong conclusions, and writing concisely.

Thesis vs. thesis statement
You may have heard the word thesis as a standalone term or as a component of academic writing called a thesis statement. Keep in mind that these are two very different things.
- A thesis statement is a very common component of an essay, particularly in the humanities. It usually comprises 1 or 2 sentences in the introduction of your essay, and should clearly and concisely summarise the central points of your academic essay.
- A thesis is a long-form piece of academic writing, often taking more than a full semester to complete. It is generally a degree requirement to complete a PhD program.
- In many countries, particularly the UK, a dissertation is generally written at the bachelor’s or master’s level.
- In the US, a dissertation is generally written as a final step toward obtaining a PhD.
How to structure a thesis
The final structure of your thesis depends on a variety of components, such as:
- Your discipline
- Your topic
- Your theoretical approach
Humanities theses are often structured more like a longer-form essay. Just like in an essay, you build an argument to support a central thesis.
In both hard and social sciences, theses typically include an introduction, literature review, methodology section, results section, discussion section, and conclusion section. These are each presented in their own dedicated section or chapter. In some cases, you might want to add an appendix.
Thesis examples
We’ve compiled a short list of thesis examples to help you get started.
- Example thesis #1: ‘Abolition, Africans, and Abstraction: the Influence of the “Noble Savage” on British and French Antislavery Thought, 1787-1807’ by Suchait Kahlon.
- Example thesis #2: ‘A Fistful of Genomes: Adventures in Comparative Genomics of Seed-Free Plants’ by David Wickell.
Title page
The very first page of your thesis contains all necessary identifying information, including:
- Your full title
- Your full name
- Your department
- Your institution and degree program
- Your submission date.
Sometimes the title page also includes your student ID, the name of your supervisor, or the university’s logo. Check out your university’s guidelines if you’re not sure.
Acknowledgements or preface
The acknowledgements section is usually optional. Its main point is to allow you to thank everyone who helped you in your thesis journey, such as supervisors, friends, or family. You can also choose to write a preface, but it’s typically one or the other, not both.

Abstract
An abstract is a short summary of your thesis. Usually a maximum of 300 words long, it’s should include brief descriptions of your research objectives, methods, results, and conclusions. Though it may seem short, it introduces your work to your audience, serving as a first impression of your thesis.
Table of contents
A table of contents lists all of your sections, plus their corresponding page numbers and subheadings if you have them. This helps your reader seamlessly navigate your document.
Your table of contents should include all the major parts of your thesis. In particular, don’t forget the the appendices. If you used heading styles, it’s easy to generate an automatic table Microsoft Word.

List of figures and tables
While not mandatory, if you used a lot of tables and/or figures, it’s nice to include a list of them to help guide your reader. It’s also easy to generate one of these in Word: just use the ‘Insert Caption’ feature.

List of abbreviations
If you have used a lot of industry- or field-specific abbreviations in your thesis, you should include them in an alphabetised list of abbreviations. This way, your readers can easily look up any meanings they aren’t familiar with.

Glossary
Relatedly, if you find yourself using a lot of very specialised or field-specific terms that may not be familiar to your reader, consider including a glossary. Alphabetise the terms you want to include with a brief definition.
Introduction
An introduction sets up the topic, purpose, and relevance of your thesis, as well as expectations for your reader. This should:
- Ground your research topic, sharing any background information your reader may need
- Define the scope of your work
- Introduce any existing research on your topic, situating your work within a broader problem or debate
- State your research question(s)
- Outline (briefly) how the remainder of your work will proceed
In other words, your introduction should clearly and concisely show your reader the “what, why, and how” of your research.
Literature review
A literature review helps you gain a robust understanding of any extant academic work on your topic, encompassing:
- Selecting relevant sources
- Determining the credibility of your sources
- Critically evaluating each of your sources
- Drawing connections between sources, including any themes, patterns, conflicts, or gaps
A literature review is not merely a summary of existing work. Rather, your literature review should ultimately lead to a clear justification for your own research, perhaps via:
- Addressing a gap in the literature
- Building on existing knowledge to draw new conclusions
- Exploring a new theoretical or methodological approach
- Introducing a new solution to an unresolved problem
- Definitively advocating for one side of a theoretical debate

Theoretical framework
Your literature review can often form the basis for your theoretical framework, but these are not the same thing. A theoretical framework defines and analyses the concepts and theories that your research hinges on.

Methodology
Your methodology chapter shows your reader how you conducted your research. It should be written clearly and methodically, easily allowing your reader to critically assess the credibility of your argument. Furthermore, your methods section should convince your reader that your method was the best way to answer your research question.
A methodology section should generally include:
- Your overall approach (quantitative vs. qualitative)
- Your research methods (e.g., a longitudinal study)
- Your data collection methods (e.g., interviews or a controlled experiment
- Any tools or materials you used (e.g., computer software)
- The data analysis methods you chose (e.g., statistical analysis, discourse analysis)
- A strong, but not defensive justification of your methods
Read more about methodology sections
Results
Your results section should highlight what your methodology discovered. These two sections work in tandem, but shouldn’t repeat each other. While your results section can include hypotheses or themes, don’t include any speculation or new arguments here.
Your results section should:
- State each (relevant) result with any (relevant) descriptive statistics (e.g., mean, standard deviation) and inferential statistics (e.g., test statistics, p values)
- Explain how each result relates to the research question
- Determine whether the hypothesis was supported
Additional data (like raw numbers or interview transcripts) can be included as an appendix. You can include tables and figures, but only if they help the reader better understand your results.
Read more about results sections
Discussion
Your discussion section is where you can interpret your results in detail. Did they meet your expectations? How well do they fit within the framework that you built? You can refer back to any relevant source material to situate your results within your field, but leave most of that analysis in your literature review.
For any unexpected results, offer explanations or alternative interpretations of your data.
Read more about discussion sections
Conclusion
Your thesis conclusion should concisely answer your main research question. It should leave your reader with an ultra-clear understanding of your central argument, and emphasise what your research specifically has contributed to your field.
Why does your research matter? What recommendations for future research do you have? Lastly, wrap up your work with any concluding remarks.
Reference list
In order to avoid plagiarism, don’t forget to include a full reference list at the end of your thesis, citing the sources that you used. Choose one citation style and follow it consistently throughout your thesis, taking note of the formatting requirements of each style.
Which style you choose is often set by your department or your field, but common styles include MLA, Chicago, and APA.
Create APA citationsCreate MLA citations
Appendices
In order to stay clear and concise, your thesis should include the most essential information needed to answer your research question. However, chances are you have many contributing documents, like interview transcripts or survey questions. These can be added as appendices, to save space in the main body.
Proofreading and editing
Once you’re done writing, the next part of your editing process begins. Leave plenty of time for proofreading and editing prior to submission. Nothing looks worse than grammar mistakes or sloppy spelling errors!
Consider using a professional thesis editing service to make sure your final project is perfect.
Defending your thesis
Once you’ve submitted your final product, it’s common practice to have a thesis defense, an oral component of your finished work. This is scheduled by your advisor or committee, and usually entails a presentation and Q&A session.
After your defense, your committee will meet to determine if you deserve any departmental honors or accolades. However, keep in mind that defenses are usually just a formality. If there are any serious issues with your work, these should be resolved with your advisor way before a defense.
Frequently asked questions about theses
- How long is a thesis or dissertation conclusion?
-
The conclusion of your thesis or dissertation shouldn’t take up more than 5-7% of your overall word count.
- How should you refer to chapters in your thesis or dissertation?
-
When you mention different chapters within your text, it’s considered best to use Roman numerals for most citation styles. However, the most important thing here is to remain consistent whenever using numbers in your dissertation.
- Is a list of abbreviations mandatory in my thesis or dissertation?
-
If you only used a few abbreviations in your thesis or dissertation, you don’t necessarily need to include a list of abbreviations.
If your abbreviations are numerous, or if you think they won’t be known to your audience, it’s never a bad idea to add one. They can also improve readability, minimising confusion about abbreviations unfamiliar to your reader.
- What is a thesis or dissertation outline?
-
A thesis or dissertation outline is one of the most critical first steps in your writing process. It helps you to lay out and organise your ideas and can provide you with a roadmap for deciding what kind of research you’d like to undertake.
Generally, an outline contains information on the different sections included in your thesis or dissertation, such as:
- Your anticipated title
- Your abstract
- Your chapters (sometimes subdivided into further topics like literature review, research methods, avenues for future research, etc.)
