🔬 Methodology11 min readUpdated 7 May 2026

The methodology chapter is where most UK dissertations are won or lost. It’s the chapter UK examiners read most carefully because it tells them whether your findings can be trusted. This guide explains how to write a strong methodology chapter for a UK dissertation in 2026, with examples for quantitative, qualitative and mixed-methods designs.

What goes in a UK dissertation methodology chapter?

A standard UK methodology chapter contains:

1. Research philosophy — your epistemological position (positivism, interpretivism, pragmatism)
2. Research approach — deductive, inductive or abductive
3. Research design — quantitative, qualitative or mixed-methods
4. Data collection method — surveys, interviews, secondary data, experiments, etc.
5. Sampling strategy — how you chose your participants
6. Data analysis approach — statistical tests, thematic analysis, discourse analysis, etc.
7. Ethical considerations — consent, anonymity, data protection
8. Limitations — what your method can’t capture
9. Trustworthiness / validity / reliability

Word count guidance

Level	Methodology word count
UG dissertation	1,500–2,500 words
Master’s dissertation	2,500–3,500 words
PhD methodology	5,000–8,000 words

Quantitative methodology — example structure

A typical UK quantitative methodology chapter:

• Positivist research philosophy
• Deductive approach
• Cross-sectional survey design
• Stratified random sampling, n = 300
• Pilot test of instrument
• SPSS for descriptive + inferential statistics
• Validity (face, content, construct), reliability (Cronbach’s alpha)
• Ethics: BPS / university ethics committee approval

Qualitative methodology — example structure

• Interpretivist research philosophy
• Inductive approach
• Phenomenological design
• Purposive sampling, n = 12 semi-structured interviews
• Thematic analysis (Braun & Clarke 2006/2022)
• Trustworthiness (Lincoln & Guba: credibility, transferability, dependability, confirmability)
• Ethics: informed consent, right to withdraw, anonymity

Mixed-methods methodology

Mixed-methods is increasingly popular in UK Master’s dissertations because it gives breadth (quant) and depth (qual). Common designs:

• Convergent parallel — quant and qual collected simultaneously
• Explanatory sequential — quant first, then qual to explain
• Exploratory sequential — qual first, then quant to test

How to justify your methodology

UK examiners want justification, not description. For every choice, answer two questions:

1. Why this approach?
2. Why not the alternatives?

“I used semi-structured interviews because they allow exploration of unexpected themes (Bryman, 2024) — unlike structured interviews, which would have constrained participants, or focus groups, which were inappropriate for the sensitive nature of the topic.”

The methodology chapter is the easiest place to demonstrate critical thinking. Every paragraph should justify a decision, acknowledge an alternative, and link back to your research question.
