Abstract :
The present study aims to introduce an exponential ratio-cum-product type class of estimators for population median under simple random sampling scheme using the supplementary variable. Expressions for the bias and Mean Square Error (MSE) were obtained up to the rst order of approximation. The proposed class of estimators was more ecient than all other considered estimators under certain conditions. Four real datasets and simulation studies were carried out to assess the performances of these estimators. Both numerical and simulation studies demonstrated that the proposed class of estimators outperformed the other considered estimators.
