The present paper gives the idea of estimating the population mean of the study variable using two auxiliary variables in double sampling. Here we have suggested a class of estimators of population mean in double sampling. The relative bias and mean square error of the proposed class of estimators are also given. An empirical study is carried out for showing the performance of the proposed class of estimators. The comparisons of the proposed class of estimators with relevant estimator are also given on the basis of their mean square error.
