To apply the Wilcoxon rank sum test to determine whether the location of population 1 is different from the location of population 2, the samples must be:

A) drawn from normal populations
B) drawn from matched pairs experiment
C) independent
D) larger than 30
E) larger than 50

Question

Willian Zhang · Accepted Answer

Final Answer : C, Explanation :  The Wilcoxon rank sum test is a non-parametric test used to determine if two independent groups are significantly different from each other. Unlike parametric tests, it does not require the assumption of normality or equal variances. Therefore, the correct answer is C, independent samples. Matched pairs experiments require the Wilcoxon signed-rank test, and there are no specific sample size requirements for this test.
