The Wilcoxon rank sum (Mann-Whitney) test is analogous to the two-sample t test for means. Both tests compare the central tendency of two groups. The Wilcoxon rank sum test is a nonparametric alternative to the t-test, making it the best choice for non-normal data. The other options are nonparametric tests, but they do not compare means directly.
