Abstract :This paper presents a double sampling version of Yadav and Kadilar (2013) estimator along with its properties under large sample approximation. Cost aspect is also discussed. We have compared the proposed estimator with usual unbiased estimator and usual double sampling ratio estimator and shown that the proposed estimator is better than usual unbiased estimator and other existing estimators under some realistic conditions to two-phase sampling.Keywords : Auxiliary variable, Bias, Efficiency, Mean squared error, Double sampling
