In this paper, a new improved calibration estimator for the population mean in a stratified sampling was proposed using … estimator with respect to three estimators considered in the literature for estimating the population mean in a stratified … sampling using two auxiliary variables. The results showed that the new estimator proved to be more efficient than the three …
