Quizplus · Accepted Answer

The Wilcoxon signed-rank test is used to compare a one-sample median with a benchmark, by testing whether the median of the differences between the sample and the benchmark equals zero or not. The Wald-Wolfowitz one-sample runs test is used to test for randomness or symmetry in a single sample, while the Wilcoxon rank sum (Mann-Whitney) test is used to compare two independent samples. The Kruskal-Wallis test is used to compare three or more independent samples.
