Frequently asked

What is the difference between methodology and methods?+

Methods are the specific techniques you use — a survey, interviews, regression. Methodology is the reasoned strategy that justifies why those methods answer your research questions, including your design, sampling and analysis logic.

How do I defend my methodology in a viva or review?+
