n = 72 subjects were randomised to 3 treatment groups: A, B, C. Measurements were taken before and after treatment. The differences were calculated between the before & after-treatment observations for the 3 treatment groups: A_diff, B_diff, C_diff. Shapiro test p-value for A_diff = 0.2567, Shapiro test p-value for B_diff = 0.007945, Shapiro test p-value for C_diff = 0.5156. What hypothesis test would I use? Repeated Measures ANOVA? Friedman's Test? Suggestions for post-hoc tests?
