Abstract

In this paper, a new product type estimator for the population mean using population correlation coefficient between the study variable and auxiliary variable has been proposed. The suggested estimator, both in first and second phase sampling,fares better than its competitors when compared with respect to bias and mean square error up to first degree of approximation. Empirical investigations have been carried out to support the theoretical findings.

Keywords

Auxiliary variable, correlation coefficient, first and second phase sampling, product type estimator, mean square error.
