Quizplus · Accepted Answer

The Wilcoxon rank-sum test is the nonparametric test for comparing two population medians under independent sampling. The other options are nonparametric tests for different scenarios, such as comparing two related samples (Wilcoxon signed-rank test), comparing more than two independent samples (Kruskal-Wallis test), and assessing randomness in a sequence (Wald-Wolfowitz runs test).
