How to Run Mann Whitney U Test in SPSS
The Mann-Whitney U test is a popular test for comparing two independent samples. That is to say, It is a nonparametric test, as the analysis is undertaken on the rank order of the scores and so does not require the assumptions of a parametric test. ( Source) The Mann-Whitney U test is a nonparametric test (data are not normally distributed).
MannWhitney U Effect Size (SPSS) YouTube
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.

The result of performing a Mann Whitney U Test is a U Statistic. For small samples, use the direct method (see below) to find the U statistic; For larger samples, a formula is necessary. Or, you can use technology like SPSS to run the test. Either of these two formulas are valid for the Mann Whitney U Test. R is the sum of ranks in the sample.
Tutorial Uji Mann Whitney dengan SPSS YouTube
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.

A Mann-Whitney U test (sometimes called the Wilcoxon rank-sum test) is used to compare the differences between two samples when the sample distributions are not normally distributed and the sample sizes are small (n <30). It is considered to be the nonparametric equivalent to the two sample t-test.
Reporting MannWhitney U Test in SPSS
The Mann-Whitney test is an alternative for the independent samples t-test when the assumptions required by the latter aren't met by the data. The most common scenario is testing a non normally distributed outcome variable in a small sample (say, n < 25). *
