3.6 The Wilcoxon- Mann-Whitney Test

For two independent samples, the analogue for one signed rank test is the Wilcoxon rank sum test proposed by Wilcoxon (1945). An equivalent test widely referred to as Whitney \(U\) test was developed independently by Mann and Whitney (1947).
It is convenient to refer to the tests jointly as the Wilcoxon-Mann-Whitney test.
