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