Research Methodology

Research methodology is the backbone of a credible study — the reasoned plan linking your questions to data and analysis. This hub explains the choices that matter and links every tool, guide and mentoring service you need to get them right.

Your methodology is where examiners and reviewers look first. It has to justify not just what you did, but why — why this design, this population, this instrument and this analysis, and not the alternatives. A sound methodology makes your findings defensible; a weak one undermines even good data.

Good methodology is a chain of aligned decisions: research design (qualitative, quantitative or mixed), sampling strategy and size, valid and reliable instruments, ethical data collection, and an analysis plan chosen before you collect anything. We mentor each link in that chain.

What this covers

Research design

Choosing and justifying a qualitative, quantitative or mixed-methods design that fits your questions, and defending it against alternatives.

Sampling & sample size

Selecting a probability or non-probability strategy and justifying a sample size adequate for your planned analysis and desired power.

Instruments & validity

Designing or adapting questionnaires and interview guides, and establishing the validity and reliability examiners expect.

Frequently asked

How do I choose a research methodology?+

Start from your research questions: they dictate whether you need to measure (quantitative), understand (qualitative) or both (mixed). The design then drives your sampling, instrument and analysis choices — each justified against the alternatives.

What makes a methodology chapter strong?+

Alignment and justification. Every choice — design, sampling, instrument, analysis — should follow logically from your questions and be defended with reasons and citations, not just described.
