Abstract:

In this paper, we have offered a class of modified ratio type variance estimator for estimation of population variance of the study variable (basic), when Tri Mean and Quartile average of the auxiliary or supplementary variable are known. The bias and mean square error (MSE) of the proposed estimator are obtained. From the numerical study it is observed that the proposed estimator performs healthier under ideal situations than the existing estimators in the literature.
