Abstract :We suggest a generalized class of estimators for the population variance using an auxiliary variable. Triphati et al. insert ignore into journalissuearticles values(T.P.

A general method of estimation and its application to the estimation of coefficient of variation, Statistics in Transition 5insert ignore into journalissuearticles values(6);, 887–908, 2002); proposed some generalized estimators for a population parameter. By adapting these estimators to population variance, we develop some estimators. We obtain the mean square error insert ignore into journalissuearticles values(MSE); equation of the proposed estimators. We illustrate the results with an application using original data.
