Question

Quizplus · Accepted Answer

The Kruskal-Wallis Test is the nonparametric equivalent of the parametric analysis of variance test. It is used to compare two or more independent groups when the dependent variable is measured on an ordinal or continuous scale, but does not meet the assumptions of normality or equal variances required for the parametric ANOVA. The Mann-Whitney-Wilcoxon Test is used to compare two independent groups, while the sign test and Wilcoxon signed-rank test are used for paired data.
