This document explains the Mann-Whitney U-test, Wilcoxon matched pairs signed rank test, Kruskal-Wallis test, and Friedman test with solved examples. The examples include testing the hypothesis that experienced podiatrists require less time than novices to make a particular diagnosis, investigating the effects of a new mobilization treatment regimen on range of movement at the ankle, comparing the change in sum of skinfolds for aerobics and control groups, and testing the reaction time for different treatments. The document provides tables, descriptive analysis, mean ranks, boxplot summary output, error plot summary output, and test statistics for each example.
