Quizplus · Accepted Answer

The Mann-Whitney U test is a nonparametric test used to compare two independent samples based on the ranks of the data rather than the actual data values. It is equivalent to the independent-samples t test, which is a parametric test, but can be used when the assumptions of the t test are not met, such as when the data are not normally distributed.
