The _____ is a nonparametric inferential test for comparing sample medians of two independent groups of scores. A)Wilcoxon matched-pairs signed-ranks T test B)Wilcoxon rank-sum test C)χ² test for independence D)χ² goodness-of-fit test

Question

Quizplus · Accepted Answer

The Wilcoxon rank-sum test, also known as the Mann-Whitney U test, is a nonparametric test used to compare the distribution of scores between two independent groups. It is based on the medians of the two groups and is appropriate for non-normally distributed data or when the assumption of equal variances is violated. Choice A is incorrect because the Wilcoxon matched-pairs signed-ranks T test is used to compare two related groups of scores. Choices C and D refer to different types of chi-square tests that are not relevant to comparing sample medians of two independent groups of scores.
