Abstract

This paper suggests a ratio-cum-product estimator of finite population mean using a correlation coefficient between study variate and auxiliary variate in stratified random sampling. Bias and mean squared expressions of the suggested estimator are derived and compared with combined ratio estimator and several other estimators considered by Kadilar and Cingi (2003). An empirical study is also carried out to examine the performance of the proposed estimator.
