The Mann-Whitney U test is equivalent to the Wilcoxon rank-sum test for independent samples in the sense
Question:
The Mann-Whitney U test is equivalent to the Wilcoxon rank-sum test for independent samples in the sense that they both apply to the same situations and always lead to the same conclusions. In the Mann-Whitney U test we calculate.
Where
Use the pulse rates listed in Table 13-5 in this section to find the z test statistic for the Mann Whitney U test. Compare this value to the z test statistic found using the Wilcoxon rank-sum test.
