Kruskal Wallis Test. Both the kruskal wallis test and one way anova assess for significant differences on a continuous dependent variable by a categorical independent variable with two or more groups. The kruskal wallis test is a non parametric test which means that it does not assume that the data come from a distribution that can be completely described by two parameters mean and standard deviation the way a normal distribution can.
It is also a popular nonparametric test to compare outcomes among three or more independent unmatched groups. It is used for comparing two or more independent samples of equal or different sample sizes. A kruskal wallist test was performed to determine if median plant growth was the same for three different plant fertilizers.

Non parametric means that the test doesn t assume your data comes from a particular distribution. The h test is used when the assumptions for anova aren t met like the assumption of normality. The kruskal wallis non parametric hypothesis test 1952 is a nonparametric analog of the one way analysis of variance. Non parametric means that the test doesn t assume your data comes from a particular distribution.
