Harald Wiese (CV) is unknown because the population mean and variance are unknown. In this study, the common mean of Gaussian distributions with unknown CVs is considered and four new interval estimators for it using generalized confidence interval (GCI), large sample (LS), adjusted method of variance estimates

Harald Wieseaboration, group formation is one of the critical factors. It often requires preparation by a teacher. In this study, to help a teacher selection grouping, we propose the models for group formation based on the principles: intra- or inter-group homogeneity or heterogeneity. It depends on the situati
