Modified Ratio Estimators for Population Mean Using Function of Quartiles of Auxiliary Variable
Abstract:
The present paper deals with some new modified ratio estimators for estimation of population mean using the quartiles and its functions of the auxiliary variable. The bias and the mean squared error of the proposed estimators are obtained and are compared with some of the existing modified ratio estimators. As a result, we have observed that the proposed modified ratio estimators perform better than the existing modified ratio estimators. These are explained with the help of numerical examples.
Keywords: Bias, Mean Squared Error, Inter-Quartile Range, Simple Random Sampling
