ABSTRACT
Product estimators of the population mean in simple random sampling and ranked
set sampling that suggested are two product estimators using the auxiliary variable
quartiles given by Al-Omari [International Journal of Human and Social
Sciences., 4 (2009), pp. 1181-1185]. These estimators are biased estimators, so
that the Mean Square Error is calculated for each estimators to obtain the efficient
estimators. The comparison showed that product estimator using rank set
sampling more efficient than product estimator using simple random sampling.
