Perform Kruskal-Wallis rank sum test of the null hypothesis that the groups \mathcal {G} G come from the same distribution against the alternative hypothesis that that at least one group stochastically dominates one other group. The Kruskal–Wallis test by ranks, Kruskal–Wallis H test (named after William Kruskal and W. Allen Wallis), or one-way ANOVA on ranks is a non-parametric method for testing whether samples originate from the same distribution.

The parametric equivalent of the Kruskal–Wallis test is the one-way analysis of …
