This shows the output of compute_aov_es from the package rwf, which takes a between-subjects aov model, builds its ANOVA table with Type I, II or III sums of squares and adds six effect sizes for every factor and interaction: eta-squared, partial eta-squared, omega-squared, partial omega-squared, epsilon-squared and Cohen’s f. Each section gives the formulas the function uses, computes them by hand and checks the results against effectsize, sjstats, car and compute_one_way_test.
