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 is used for comparing the medians of two groups, while the other two options are not relevant to this scenario.
