Use the KruskalWallisTest class to test whether a
number of samples come from the same population. This test can be thought
of as a non-parametric variation of one-way analysis of variance that
doesn't assume the data is normally distributed.
This class approximates the distribution of the test statistic
by a beta distribution.
This approximation has been found to be more accurate than the traditional
chi-square approximation.
Still, for small sample sizes, critical values and
tail probabilities may differ significantly from their exact values.
