Ranked set sampling (RSS) as suggested by McIntyre (1952) uses fixed set size and number of cycles (or replications). In real life however, we may encounter problems that requiring random set size or number of cycles or both. In dealing with such problems we suggest several unbiased estimators of the population mean using random ranked set sampling (RRSS) method. The efficiencies of the estimators of the population under RRSS and RSS are compared. The results show, under certain conditions, the efficiency of estimators is improved by using RRSS. The asymptotic properties of the newly suggested estimators are also considered.
