A comprehensive collection of revision notes for Research Methods as part of AQA A Level Psychology. These notes cover both AO1 and AO3 (evaluation) for both year 1 and 2 topics. The notes cover the following: experiments, sampling methods, correlations, types of data, descriptive statistics, inferential statistics, observations, self-report methods, case studies, qualitative data, pilot studies, reliability, validity, ethics, sections of a report, peer review, theory construction, and paradigms. I wrote these notes for my A levels in 2021 in which I received an A* and have since used them to teach A level Psychology for the past year.
