Quizplus · Accepted Answer

Both the Mann-Whitney U test and the independent samples t-test compare two groups, but the Mann-Whitney U test is a non-parametric test that does not assume normality, while the independent samples t-test assumes normality of the data. Similarly, the Spearman rank-ordered correlation coefficient is a non-parametric measure of correlation, while the Pearson correlation coefficient assumes normality of the data. Therefore, the best choice for completing the analogy is the independent samples t-test.
