Use the LeveneTest class to test whether 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 can also be used for this purpose. However, Levene's test is more robust against departures from normality. On the down side, Levene's test is slower than Bartlett's test. If there is strong evidence that the data is, in fact, distributed normally, then Bartlett's test is usually preferred.
