A Level OCR Psychology statistics resource, each slide gives a step-by-step outline of how to calculate the 5 non-parametric stats tests (Chi-Square, binomial sign test, Wilcoxon, Spearman’s rho and Mann-Whitney U). My students have found it useful to print the slides as flashcards and use for revision or as an aid to refer to when practicing statistics questions. Also relevant for other A level subjects which require knowledge of how to calculate these tests.
