Mann Whitney U test | Numerical Example with Step by Step Calculation | Non Parametric Statistics

The Mann-Whitney U test is a non-parametric test that can be used to analyse data from a two-group independent groups design when measurement is at least ordinal. It analyses the degree of separation (or the amount of overlap) between the Experimental (E) and Control (C) groups. The null hypothesis assumes that the two sets of scores (E and C) are samples from the same population; and therefore, because sampling was random, the two sets of scores do not differ systematically from each other. The alternative hypothesis, on the other hand, states that the two sets of scores do differ systematically. If the alternative is directional, or one-tailed, it further specifies the direction of the difference (i.e., Group E scores are systematically higher or lower than Group C scores).
