Research Methods for HL

This is a complete, fully resourced IB DP Psychology Research Methods resource for Paper 3 HL students, designed for the new specification first assessed in 2027. The resource is structured around the demands of Paper 3, with clear support for graph interpretation, data analysis, research considerations and synthesis/evaluation. It includes all core explanations, examples, diagrams, data interpretation guidance, research-method summaries and exam-focused terminology, so no additional teacher input is needed.

The resource supports students in understanding quantitative and qualitative research, including bar graphs, box and whisker plots, distributions, frequency tables, histograms, line graphs, outliers, scatterplots, descriptive statistics, inferential statistics, correlation coefficients and thematic analysis. It also covers key Paper 3 research considerations, including credibility, bias, transferability, reliability, validity, generalisability and reflexivity.

The booklet also includes clear explanations of the main research methods used in psychology, including experiments, observations, surveys/questionnaires, interviews, correlational studies and case studies, alongside sampling techniques and methodological strengths and limitations. This makes it ideal for teachers who want a ready-to-use HL Paper 3 research methods booklet and for students who need structured, accessible support with interpreting sources, analysing data and evaluating research claims.
