In this paper a study is conducted to investigate the power\u0000of several goodness of fit tests such as Kolmogorov Smirnov (KS),\u0000Anderson-Darling(AD), Cramer- von- Mises (CV) and a proposed\u0000modification of Kolmogorov-Smirnov goodness of fit test which\u0000incorporates a variance stabilizing transformation (FKS). The\u0000performances of these selected tests are studied under simple\u0000random sampling (SRS) and Ranked Set Sampling (RSS). This\u0000study shows that, in general, the Anderson-Darling (AD) test\u0000performs better than other GOF tests.
