Remarks

Use the BartlettTest class to test the hypothesis that a number of samples have the same variance. This property is called homogeneity of variance.

Some statistical procedures, such as the Analysis of Variance, assume that variances are the same across groups.

Bartlett's test is a relatively fast test for homogeneity of variances. The test is based on the assumption that the samples are normally distributed. It is sensitive to violations of this assumption. In practical terms, this means that Bartlett's test cannot adequately distinguish between violation of homogeneity of variances and violation of the normality assumption. In such a case, Levene's test gives more meaningful results.
