Abstract

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