 ABSTRACT

The present study was taken under consideration in order to propose new modified estimators using different linear combinations for population mean using the auxiliary information of Mid-Range with coefficient of correlation, coefficient of variation and coefficient of skewness in order to achieve more precision in estimates than the already existing estimators. The properties associated with the proposed estimators are assessed by mean square error and bias and compared with the existing estimators. In the support of the theoretical proposed work we have given numerical illustration.

Keywords: Auxiliary information, Linear combinations estimators, Mean square error, Bias, Efficiency.
