Abstract

In this paper, ranked set sampling (RSS), median ranked set sampling (MRSS) and double median ranked set sampling (DMRSS) methods are used for estimating the population mean based on a modified ratio estimator. It is found that, RSS, MRSS and DMRSS produce approximately unbiased estimators of the population mean and these estimators are more efficient than those obtained using simple random sampling (SRS) based on the same sample size. Also, it is found that, DMRSS is more efficient than both RSS and MRSS methods.
