Compare Multiple Independent Samples [Kruskal-Wallis, Median Test]...

The Kruskal-Wallis ANOVA is a non-parametric method to test if samples are from the same distribution. The test is similar to the parametric one-way ANOVA, except that it is based on ranks rather than means. Median test checks the null hypothesis that the medians of the populations from which two or more samples are drawn are identical.
