About Mann-Whitney U Test
The Mann-Whitney U test is a non-parametric test that compares two independent samples to determine whether they come from the same distribution.
It is used when the assumptions of the independent t-test are not met (e.g., non-normal distributions).
The test ranks all observations and compares the sum of ranks between groups.
