Abstract: The paper comprises an estimator for estimating population variance using auxiliary information as median, since auxiliary information correlated with the study variable boosts the efficiencies of the estimators.Simple random sampling without replacement scheme has been applied as a technique.The proposed estimator's mean squared error is derived up to the first order of approximation and the obtained efficiency is collated with some of the existing estimators mentioned in the literature.On the basis of result obtained from the simulation study that has been performed for the result's confirmation.It has seen that proposed estimator has better efficiency and hence works better than the existing estimators.
