Quizplus · Accepted Answer

The Mann-Whitney U test is a nonparametric alternative to the independent samples t-test. It is used when the assumptions of normality and equal variances are not met. It tests whether there is a significant difference between two independent groups based on their ranks on a single, continuous outcome variable. Therefore, Mann-Whitney U is the best choice among the given options.
