Ratio Type Estimator of Population Mean in Double Sampling

Kaiser Ahmed Malik, Rajash Tailor


This paper discusses the problem of estimation of population mean in double sampling. In fact, in this paper double sampling version of (Singh and Tailor, 2003) has been suggested. The bias and mean squared error of the suggested estimators are obtained up to the first degree of approximation. The suggested estimator has been compared with simple mean estimator and double sampling ratio estimator. An empirical study has been carried out to demonstrate the performance of the suggested estimator.
