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.

Early clockmakers apparently thought that the IIII balanced out the VIII (used for the number 8) on the clock face and that it just looked better.
