This paper proposes an exponential estimator of a population mean under double sampling using one auxiliary variable.The proposed estimator is modified from the estimator of Khatua and Misha (2013) and Ozgul IEC Mains Power Lead and Cingi (2014).The bias and mean square error of the proposed estimator are derived under the second order of approxima
