In the Wilcoxon rank-sum test, the null hypothesis may be expressed as:

​

\(\style{font-family:Times New Roman;}{H_0:\;{\overset˜\mu}_1-{\overset˜\mu}_2=\Delta_{\text{o}}}\)

​

If\(\style{font-family:Times New Roman;}{\Delta_{\text{o}}=0}\), then:


◦

the test is not valid.


◦

we can conclude that the null hypothesis is true and there is no difference in the two population medians only if the sample provides sufficient support for this assertion.


◦

there is insufficient evidence to reject the null hypothesis, but nothing is said about the validity of the null hypothesis.


◦

the median of population 1 is equal to the mean of population 2, provided both populations are heavily skewed.
