A two-sample t-test with independent samples corresponds to:
A) a Wilcoxon signed rank test for paired samples
B) a Wilcoxon rank sum test
C) a Wilcoxon signed rank test for one sample
D) a Friedman test for randomized block design
E) a chi-square test

Question

Quizplus · Accepted Answer

A two-sample t-test with independent samples is used to compare the means of two independent groups, which is equivalent to a Wilcoxon rank sum test. Option A is incorrect because the Wilcoxon signed rank test is used for paired samples, where the same subjects are measured twice. Option C is incorrect because the Wilcoxon signed rank test for one sample is used to compare the median of a single group to a hypothesized value. Option D is incorrect because the Friedman test is used for blocked or repeated measures designs with three or more groups. Option E is incorrect because a chi-square test is used for categorical data, not continuous data.
