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.
