| Summary: | This study presents a proposal to estimate the finite population's mean of the main variable by median ranked set sampling through the generalized ratio-cum-product type exponential estimator. The relative bias , mean squared error and percentage relative efficiencies of the proposed estimator is obtained to the first degree of approximation. The proposed estimator are more efficient than the usual unbiased estimator, ratio, product type, and other estimators. Finally, the estimators' abilities are evaluated through simulations, showing that the proposed estimator is more efficient than several other estimators. |
