Abstract

In this paper exponential ratio type estimators have been proposed for population mean using two phase equal probability sampling with single and two auxiliary variables in case of no information. The proposed estimators are compared with the estimators given by Sukhatme (1962), Singh and Vishwakarma (2007) and Hanif et al. (2009). It is found that the proposed estimators are relatively more efficient than these estimators for all types of populations.
