Quizplus · Accepted Answer

The Mann-Whitney U test is a non-parametric test that evaluates ordinal data from two independent groups. It is used when the assumptions necessary for the t-test for independent groups are violated, such as non-normal data or unequal variance. The chi-square test is used to evaluate categorical data, the t-test for independent groups is used to evaluate continuous data, and the Wilcoxon test is used to compare paired data.
