Ratio cum Median Based Modified Ratio Estimator for the Estimation of Finite Population Mean with Known Coefficient of Variation and Correlation Coefficient
Srija International Journal of Computer & Mathematical Sciences IJCMS
The present paper discusses some ratio cum median based modified ratio estimators for estimating the finite population mean with known parameters of the auxiliary variable such as coefficient of variation and correlation Coefficient and their linear combinations. The performances of the proposed estimators are assessed with that of simple random sampling without replacement (SRSWOR) sample mean and ratio estimator in terms of their variances and or mean squared errors.
