The nonparametric counterpart of the parametric t-test of $\mu$_D for matched pairs is the: A) Friedman test. B) Kruskal-Wallis test. C) Wilcoxon signed rank sum test. D) Wilcoxon rank sum test.

Question

Quizplus · Accepted Answer

The Wilcoxon signed rank sum test is used as a nonparametric alternative to the parametric t-test for matched pairs or repeated measures. It compares the distribution of differences between paired observations to a null hypothesis that the median of the differences is zero. The Friedman test is a nonparametric alternative to the one-way ANOVA for repeated measures. The Kruskal-Wallis test is a nonparametric alternative to the one-way ANOVA for independent samples. The Wilcoxon rank sum test is a nonparametric alternative to the two-sample t-test for independent samples. None of these tests are appropriate alternatives for the matched pairs t-test.
