This paper suggests the difference method of estimation of the population mean of the study variable using information on an auxiliary variable with its properties. The optimum estimator in the suggested method has been identified alongwith its mean square error formula. It has been identified that the suggested method is more general and efficient than(More)
This paper addresses the problem of estimating the population variance of variable of interest using information on an auxiliary variable in sample surveys. A new class of ratio-type estimators is proposed. In addition to some existing estimators, large number of consistent and inconsistent estimators has been identified as a member of the proposed class of(More)
The present paper discusses the problem of estimating the finite population mean in simple random sampling. A class of estimators has been proposed using information on an auxiliary variable and its properties are studied. It has been shown that the proposed class of estimators is more efficient than the usual unbiased, ratio and product estimators. An(More)
