Advanced Stats with SPSS Mann Whitney U Test effect size (eta squared)
A Mann-Whitney U test is a non-parametric alternative to the independent (unpaired) t-test to determine the difference between two groups of either continuous or ordinal data.

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.

A Mann-Whitney U test (sometimes called the Wilcoxon rank-sum test) is used to compare the differences between two independent 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 independent t-test.

Unlike the independent-samples t-test, the Mann-Whitney U test allows you to draw different conclusions about your data depending on the assumptions you make about your data's distribution.

Step 3: Interpret the results. Once you click OK, the results of the Mann-Whitney U Test will be displayed: The most important numbers in the output are the Z test statistic and the Asymptotic 2-tailed p-value: Since the p-value is not less than 0.05, we fail to reject the null hypothesis.

The homogeneity of the 2 groups at the baseline evaluation was carried out by using the Student t-test and Mann-Whitney U-test for continuous variables and by the chi-square test for categorical variables.
MannWhitney U Effect Size (SPSS) YouTube
The Mann-Whitney U test procedure uses the rank of each case to test whether the groups are drawn from the same population. Mann-Whitney tests that two sampled populations are equivalent in location. The observations from both groups are combined and ranked, with the average rank assigned in the case of ties. The number of ties should be small.
