Abstract

In this paper one of the basic techniques of sampling namely simple random sampling has been used utilizing R software keeping in view the importance of this technique in agricultural surveys. Apple data taken from district Ganderbal of Kashmir valley is taken. Function SRSWOR(Y,N) using R software is developed; also different graphics are presented.

Abstract

In this article we have proposed some ratio estimator for the study variable based on the linear combination of known values of Co-efficient of Skewness and Median of the auxiliary variable utilizing Rank set sampling and Simple random sampling are proposed. Mean squared error up to the first degree of approximation are derived. The proposed ratio estimators under rank set sampling perform better than the proposed ratio estimators under simple random sampling. The simulated study has been carried out in support of the results.
