Abstract
This article discusses the three ratio estimators for population mean in simple random
sampling by using the auxiliary variable of the quartiles, proposed by Subramani and
Kumarapandiyan. These three discussed estimators are biased estimators. The mean
square errors of the discussed estimators are compared to obtain the most efficient
estimator. The comparison shows that the ratio estimator by using inter-quartile range is the most efficient estimator than the other two estimators. A numerical example is given to explain the discussed problem.
