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.
