Hartley-Ross type unbiased estimators using the stratiffed random sampling

Abstract

This study mentions Hartley-Ross type unbiased ratio estimators ofthe finite population mean in the stratiffed random sampling using theauxiliary variable. We propose the unbiased estimators using the estimatorsin Kadilar and Cingi [5],[6]. We derive the variance equations,up to the first degree of approximation, for all proposed estimators.The proposed estimators have been compared with the mentioned estimatorsin theory. Finally, we also demonstrate theoretical findings bythe support of numerical illustrations.
