Statistics U or U' in the Mann-Whitney U test, measure the differences between the means of the two groups

In a test with two groups, the smaller value between the statistics U and U' points to the research hypothesis, while the larger value points to the alternative hypothesis.

The formula to calculate U and U' is:

[tex]U = n_1 \times n_2 + \frac{n_1(n_1+1)}{2} - R_1[/tex]

[tex]U' = n_1 \times n_2 + \frac{n_2(n_2+1)}{2} - R_2[/tex]

Take, for instance;

The values of U and U' in a test where the research hypothesis of two populations are not equal are:

[tex]U = 0[/tex]

[tex]U' = 22[/tex]

Recall that, the smallest of the 2 value supports the research hypothesis.

This means that [tex]U = 0[/tex] shows that the difference in the population is 0.
