Since our test statistic 13 is greater than our critical value 5 we fail to reject the null hypothesis. So for example one might compare the speed at which two different groups of people can run 100 metres where one group has trained for six weeks and the other has not. Dashes indicate that the sample size is too small to reject the null hypothesis at the chosen α level. The mann whitney u test is a nonparametric test that allows two groups or conditions or treatments to be compared without making the assumption that values are normally distributed.
