Kruskal-Wallis test is a nonparametric test that can be used to compare more than two independent samples when the assumptions for an analysis of variance are invalid.
Nonparametric Test
A type of statistical test that does not assume a particular distribution for the data, often used when data do not meet the assumptions of parametric tests.
Independent Samples
Two or more groups of data that are collected from different populations or treatment conditions, with no overlapping members between groups.
