Ranked Set Sampling is used when taking exact measurement of sampling units is difficult but ranking is easy. Stratified sampling is a sampling method when the population is heterogeneous. In this thesis, the classical, ratio and exponential estimators of population mean is studied under various stratified ranked set sampling which use both sampling techniques. The performances of recently proposed new stratified ranked set sampling methods and classical methods are compared by using body mass index data set. The efficiency of mean estimators which is suggested in sampling designs is examined by a simulation study. We conclude that new stratified ranked set sampling methods perform better than stratified random sampling.
