A simulation study of a test for the equality of the coefficients of variation

Simulation study results are given for the size and power of a test for the equality of the coefficients of variation from r normal populations. Independent samples of equal and unequal size from the normal and three other distributions were used. The size and power of the test compare favorably to two tests developed by Doornbos and Dijkstra and the test statistic is simpler to compute.
