The Mann-Whitney test is a non-parametric alternative to Student's t-test (StudentTTest(Sample, Sample)). Essentially, it supposes that the medians of the two samples are equal and tests the likelihood of this null hypothesis. Unlike the t-test, it does not assume that the sample distributions are normal.
