|Oct 2015Abstract
In the present study, I propose a modified estimator for estimating the population mean of the study variable auxiliary information when the population mean and the population median of the auxiliary variable is known. The expression of bias and mean squared error (MSE) of the proposed estimator is derived. Some existing estimators are also discussed. Comparisons of the proposed estimator with the other estimators are carried out. The results obtained are illustrated numerically by using three natural populations considered in the literature.
