- Abstract
In the present paper, stratified mixture ranked set sampling (SMIRSS) for estimation of the population mean and median is suggested. The SMIRSS provides unbiased estimator of population mean for symmetric distribution. To test the performance of estimators under suggested scheme a simulation study is conducted. The simulation results indicate that the SMIRSS is more efficient than the stratified extreme ranked set sampling (SERSS) and stratified simple random sampling (SSRS) designs. Moreover, in small sample the suggested scheme is more efficient than stratified ranked set sampling (SRSS) for some distributions.
