The ranked set sampling method (RSS) as suggested by Melntyre (2952) may be modified to yield new sampling methods with improved efficiency. Several modifications for the RSS are introduced by several authors such as extreme ranked set sampling (ERSS) suggested by Samawi et al. (1996), median ranked set sampling (MRSS), suggested by Muttlak (1997), etc. In this study a few other modifications for the RSS are introduced and compared to the RSS, ERSS and MRSS. It turns out that for probability distributions considered in this study, efficiency of RSS can be improved by using some sort of modification for the RSS method.
