What is a methodology?

Your methodology section appears immediately after the literature review in your dissertation, and should flow organically from it. Up until the point of writing your methodology, you will have defined your research question and conducted a detailed review of what other scholars in the field have to say about your topic. You’ll have also reviewed the ways in which these scholars have arrived at their conclusions – the assumptions on which their work is based, the theoretical frameworks they've used, and the methods they've used to gather, marshal and present their data. You will have used these observations, along with discussions with your supervisor, to plan how you're going to tackle your research question. This could be planning how you'll gather data, or what models you'll use to process it, or what philosophical positions most inform your work. Following this, your dissertation methodology provides a detailed account of both how you'll approach your dissertation and why you've taken the decision to approach it in the way you have.

What should my methodology look like?

Your methodology of a dissertation needs to establish a clear relationship between your research question, the existing scholarship in your field that you have surveyed as part of your literature review, and the means by which you'll come to your conclusions. Therefore, no matter what subject area you're working in, your methodology section will include the following:

• A recap of your research question(s)

  Key to justifying your methodology is demonstrating that it is fit for the purpose of answering the research problem or questions you posed at the start. You should recap the key questions you want to answer when introducing your methodology, but this doesn't have to be a word-for-word restatement; you might want to reword the problem in a way that bridges your literature review and methodology.

• A description of your design or method

  This is the heart of the methodology but is not, by itself, a methodology. This is the part of your methodology where you clearly explain your process for gathering and analysing data, or for approaching your research question. This should be clear and detailed enough that another scholar is able to read it and apply it in some way, outside of the immediate context of your dissertation. If you're offering a new theoretical take on a literary work or a philosophical problem, your reader should be able to understand your theory enough that they can apply it to another text or problem. If you're describing a scientific experiment, your reader should have all they need to recreate your experiment in a lab. If you're introducing a new type of statistical model, your reader should be able to apply this model to their own data set after reading your methodology section.

• The background and rationale for your design choice

  Your methodology doesn't just describe your method; it discusses the reasons why you've chosen it, and why you believe it will yield the best results, the most insightful set of analyses and conclusions, or the most innovative perspective. This will draw in part from your literature review, presenting your choices as informed and rooted in sound scholarship, while ideally also displaying innovation and creativity. You should also ensure that you relate the rationale for your method explicitly to your research problem; it should be very clear to your reader that the methodology you've chosen is a thoughtful and tailored response to the questions you're trying to answer.

• An evaluation of your choice of method, and a statement of its limitations

  No research method is perfect, and it's likely that the one you've chosen comes with certain trade-offs. You might, for instance, have chosen a small-scale set of interviews because the individual perspectives of a set of interviewees on the problem you're exploring is more valuable to you than a larger set of data about responses to the same question. But that means you've nevertheless sacrificed a quantitative approach to your problem that might have yielded its own set of important insights. Be honest and upfront – but not apologetic – about the limitations of your chosen method, and be ready to justify why it's the best approach for your purposes.

While the outline of your methodology section will look much the same regardless of your discipline, the details are liable to be quite different depending on the subject area in which you're studying. Let's take a look at some of the most common types of dissertation, and the information required in a methodology section for each of them.
