The nonparametric counterpart of the parametric t-test of  for matched pairs is the:
A) Friedman test 
B) Kruskal-Wallis test 
C) Wilcoxon signed rank test 
D) Wilcoxon rank sum test 
E) chi-square test

Quizplus · Accepted Answer

The Wilcoxon signed rank test is the nonparametric counterpart of the parametric t-test for matched pairs, as it is used to compare two related or matched groups. The Friedman and Kruskal-Wallis tests are nonparametric tests for independent groups, while the Wilcoxon rank sum test is a nonparametric test for independent groups without a matched or related design. The chi-square test is used for categorical data. Therefore, choice C is the best option.
