Quizplus · Accepted Answer

The Kruskal-Wallis Rank Test is the appropriate nonparametric procedure for comparing the median response time for three independent groups. The Wilcoxon Rank Sums Test and the McNemar Test are appropriate for comparing two independent groups and two dependent groups respectively, but not for three independent groups. The χ² test is not a recognized statistical test.
