Seminar by Kazeem Adepoju, University of Minnesota

Abstract

The Classical F(CF) test relies on three major underlying assumptions namely; non overlapping of the populations, constancy of variance and absence of outliers. These assumptions had been violated because of the presence of outliers in observations or  due to other causes. Previous attempts to address these violations resulted in the inflation of type I error, because the conventional F table is still being used by researchers in decision making. This study therefore was designed to develop a modified robust Exponentiated F test and generate its corresponding modified statistical table for decision making on one way analysis of variance (ANOVA) tests in the presence of heteroscedasticity.
