The parametric equivalent of the Kruskal–Wallis test is the one-way analysis of variance (ANOVA). A significant Kruskal–Wallis test indicates that at least one sample stochastically dominates one other sample. The test does not identify where this stochastic dominance occurs or for how many pairs of groups stochastic dominance obtains.
The most common non-parametric test for the one-factor model is the Kruskal-Wallis test. The Kruskal-Wallis test is based on the ranks of the data. The advantage of the Van Der Waerden test is that it provides the high efficiency of the standard ANOVA analysis when the normality assumptions are in fact satisfied, but it also provides the ...
The Kruskal-Wallis test is indeed, in its most general application, a test of the null hypothesis that there is no stochastic dominance between any of the groups tested (i.e. H0: P(X i > X j) = 0.5 for all groups i and j, with HA: P(X i > X j) ≠ 0.5 for at least one i ≠ j). These hypotheses, and this test are not about means. I have cleaned ...
Statistical tests are used to test the fit between a hypothesis and the data. [1] [2] Choosing the right statistical test is not a trivial task. [1]The choice of the test depends on many properties of the research question.
William Henry Kruskal (/ ˈ k r ʌ s k əl /; October 10, 1919 – April 21, 2005) was an American mathematician and statistician. He is best known for having formulated the Kruskal–Wallis one-way analysis of variance (together with W. Allen Wallis ), a widely used nonparametric statistical method .

It is an extension of the Kruskal–Wallis test, the non-parametric equivalent for one-way analysis of variance , to the application for more than one factor. It is thus a non-parameter alternative to multi-factorial ANOVA analyses. The test is named after James Scheirer, William Ray and Nathan Hare, who published it in 1976. [1]
