Abstract
This paper discusses two product estimators for the population mean in the random sampling, those are the product estimator in simple random sampling and product estimator in ranked set sampling using the auxiliary variable quartiles given by Al-
Omari [International Journal of Human and Social Sciences., 4 (2009), pp. 1181-1185]. The two estimators are biased estimators. The most efficient estimator is the estimator that has the smallest mean square error obtained by comparing the mean square error of each estimator.
