Statistics: 2.3 The Mann-Whitney U Test - statstutor

Note that the Mann-Whitney U test is statistically equivalent to the Wilcoxon rank sum test (not to be confused with the Wilcoxon signed rank sum test, which is for paired data). Example: The following data shows the age at diagnosis of type II diabetes in young adults. Is the age at diagnosis different for males and females? Males: 19 22 16 29 24
