Abstract:

The usual F-test on variances has been shown to be non-robust when the underlying populations are not normally distributed. An alternative test for equality of variances is developed and compared with the F-test by means of sampling experiments. This alternative test is shown to be less seriously affected by non-normal populations than is the F-test and a brief comparison of this alternative test and a modified F-test developed earlier is given.
