Comparing Multiple Indep. Samples (Groups)

Nonparametric comparisons of multiple groups; computes Kruskal-Wallis ANOVA and Median tests for each continuous (dependent or predictor) variable, from the codes in a single categorical predictor variable. Multiple (post-hoc) comparisons of average ranks, box-whiskers plots, and categorized histograms can also be computed.

General

Element Name Description
Multiple comparisons Computes multiple comparisons of the average ranks for each pair of groups; normal z-values will be computed for each comparison, as well as post-hoc probabilities (corrected for the number of comparisons) for a two-sided test of significance.
Box and whiskers plot Creates box and whiskers plots for the dependent variables; one box plot for each comparison (continuous dependent variable) will be produced.
Categorized histogram Creates categorized histogram for continuous dependent variables.
