How to Write a Dissertation Methodology

The methodology chapter is where you explain and justify how you conducted your research. It is one of the most technically demanding chapters of a UK dissertation because it requires you to demonstrate familiarity with research philosophy, design and methods - and to make a convincing argument for the choices you made. A methodology chapter is not just a description of what you did; it is a critical justification of why you did it that way, with reference to academic literature on research methods.

Research philosophy

Most UK postgraduate dissertations require you to state and justify your research philosophy (also called paradigm or ontological position). The main positions are positivism (reality is objective and measurable, typically associated with quantitative research), interpretivism (reality is socially constructed and context-dependent, typically associated with qualitative research) and pragmatism (research philosophy is chosen based on what works best for the research question, associated with mixed methods). You do not need to write at length on philosophy for undergraduate work unless your module specifically requires it.

Research approach: deductive vs inductive

A deductive approach begins with theory and tests it with data - common in quantitative studies. An inductive approach begins with data and builds theory from it - common in qualitative studies. An abductive approach moves back and forth between theory and data, common in interpretivist research. Identify which approach your study uses and explain why it is appropriate for your research questions. These terms appear frequently in methodology marking criteria.

Research design and strategy

Your research design is the overall structure of your study. Common designs in UK dissertations include: case study (in-depth examination of a specific case or organisation), survey (collecting data from a sample through questionnaires), ethnography (immersive observation of a group or culture), experiment (testing variables under controlled conditions), and action research (practitioner-researcher cycles of reflection and change). Your strategy determines how you will collect and analyse data within your chosen design.

Data collection methods

Describe your data collection method in detail: how you collected data, from whom, using what instruments, and over what time period. For interviews: explain whether they were semi-structured or unstructured, how many participants, how they were recruited and how long each lasted. For surveys: explain question design, distribution method, sample size and response rate. For secondary data: explain what sources you used, why they are credible and what period they cover. Always link your method back to your research questions.

Sampling, ethics and limitations

Explain your sampling strategy: purposive, convenience, snowball, random, stratified - and justify why this was appropriate for your study. Discuss the size of your sample and why it is sufficient. Address ethics: how did you obtain informed consent, how did you protect anonymity, how was data stored, and was ethical approval required from your institution? Close the chapter with an honest discussion of methodological limitations - this is not a weakness but a sign of critical self-awareness that markers reward.

Key tips

  • Cite methods literature throughout - Saunders, Lewis and Thornhill's Research Methods for Business Students is a widely accepted source.
  • Write your methodology in past tense if you have already completed the research, or future tense for a proposal.
  • Never justify a method simply because it was 'easier' - always give an academic rationale.
  • Your ethical considerations section should show awareness even if your research poses minimal risk.
  • Limitations are not failures - acknowledge them and explain how you minimised their impact.
