Hartley-ross type unbiased estimators using the stratified random sampling

This study mentions Hartley-Ross type unbiased ratio estimators of the _nite population mean in the strati_ed random sampling using the auxiliary variable. We propose the unbiased estimators using the estimators in Kadilar and Cingi [5],[6]. We derive the variance equations, up to the _rst degree of approximation, for all proposed estimators. The proposed estimators have been compared with the mentioned estimators in theory. Finally, we also demonstrate theoretical _ndings by the support of numerical illustrations.
