Kruskal-Wallis is the nonparametric equivalent of a one-way ANOVA with multiple groups. It is used when the normality assumption is violated or the data are ordinal or nominal. The Friedman test is used for repeated measures designs, Phi coefficient is used for nominal data to measure association, and Wilcoxon is used for two-group comparisons.
