| Abstract | ||||
| The robustness of Welch-Aspin test and Lee-Gurland test developed for testing the equality of means of two normal populations with unknown variances is considered. for selected samples sizes, the size and power of each test are computed empirically under normality and under nonnormal parent populations. | ||||
