摘要：In this paper, we have proposed to use two classes of sampling strategies based on themodified ratio estimator using the standard deviation and the coefficient of skewness of theauxiliary variable by Singh (2003) for estimating the population mean (total) of the studyvariable in a finite population. The properties of the proposed sampling strategies are studied andsome concluding remarks are given. Als o, an empirical study is included as an illustration
