Abstract

In this study we have introduced a new reliable and robust ratio estimator for estimating the population variance by utilizing the auxiliary information as Gini’s mean difference. Efficiency conditions along with bias and mean square error has been worked out through a numerical demonstration under which proposed estimator have proven better than the existing estimators under consideration.

Keywords: Ratio estimator, Gini’s mean difference, SRSWOR, MSE, bias and efficiency
