The nonparametric counterpart of ANOVA is the ________.

a. Wilcoxon signed-rank test
b. Sign test
c. Runs test
d. None of the above

Solutions

Expert Solution

(d) None of the above

 

Explanation:

The nonparametric counterpart of ANOVA is Kruska-Wallis test. The analysis of variance (ANOVA) uses the F test to compare the means of three or more populations. The assumptions for the ANOVA test are that the populations are normally distributed and that the population variances are equal. When these assumptions cannot be met, the nonparametric Kruskal-Wallis test, sometimes called the H test, can be used to compare three or more means.

The right option is (d).
