Abstract :In this article, a testing procedure based on computational approach testis proposed for the equality of coefficients of variation in k normal populations. We compare this procedure to some of the existing tests; the likelihood ratio, modified Bennett’s, score, generalized p -value tests in terms of the estimated type I error rates and powers by using Monte Carlo simulation. Furthermore, applications of these tests are given on a real dataset.Keywords : Computational approach test, Generalized p-value test, Likelihood ratio test, Modified Bennett’s test, Score test
