How to Run Mann Whitney U Test in SPSS
A Mann-Whitney test is used when we have a continuous level variable measured for all observations in two groups and we want to test if the distribution of this variable is different in the two groups but we are unable to assume normality in both groups. It can also be used to compare an ordered categorical variable measured on two groups.

The Mann Whitney U test is a nonparametric hypothesis test that compares two independent groups. Statisticians also refer to it as the Wilcoxon rank sum test. The Kruskal Wallis test extends this analysis so that can compare more than two groups. If you're involved in data analysis or scientific research, you're likely familiar with the t-test.
