On The Use of Analysis of Variance under Unequal group variances

East Asian Journal of Multidisciplinary Research, 2023
In this study, we imposed Analysis of variances test (ANOVA) which use when we have more than two treatments or different levels of a single factors that we wish to compare then we assume homogeneity of variances across the groups being compared although most of the earlier works that have addressed the problem of testing equality of mean variance ...
