Mann–whitney–wilcoxon
WebA good example of a non-parametric test is the Mann-Whitney U-test (Also known as the Mann-Whitney-Wilcoxon (MWW) or Wilcoxon Rank-Sum Test). Unlike its parametric counterpart, the t-test for two samples, this test does not assume that the difference between the samples is normally distributed, or that the variances of the two populations … WebThe Wilcoxon Sign test is a statistical comparison of the average of two dependent samples. The main difference is that the Mann-Whitney U-test tests two independent …
