Bartletts homogeneity-of-variance test.* Suppose there are k independent sample variances s 2 1 , s 2 2
Question:
provides an estimate of the common (pooled) estimate of the population variance Ï2, where fi = (ni 1), ni being the number of observations in the ith group and where f Σki = 1 fi . Bartlett has shown that the null hypothesis can be tested by the ratio A/B, which is approximately distributed as the Ï2 distribution with k 1 df, where
And
Apply Bartletts test to the data of the following table and verify that the hypothesis that population variances of employee compensation are the same in each employment size of the establishment cannot be rejected at the 5 percent level of significance. Note: fi, the df for each sample variance, is 9, since ni for each sample (i.e., employment class) is 10.
