The test statistics that are used to test hypotheses, which are about the equality of the coefficients of variation, have been introduced and compared . A simulation has been prepared for the comparative study. The simulation has been designed for a different numbers of population (k=2, 3, 4, 5 and 6), a different sample sizes (n=10, 15, 20, 30, 40, 50 and 100) and a different levels of type I. error ( =0,01, 0,05 and 0,10). The purpose of the study is to compare the test statistics that are used to test the equality of coefficient of variation in terms of type I. error and the power of the test.…mehr
