Quizplus · Accepted Answer

The Wilcoxon signed-rank test is the nonparametric equivalent of the related samples t-test. It is used to compare the median difference between two related populations. The Mann-Whitney U test, Kruskal-Wallis H test, and Friedman test are all nonparametric procedures, but they are used for different types of comparisons (independent samples, more than two related samples, and more than two related samples with repeated measures, respectively).
