In sample surveys, it is usual to make use of auxiliary information to increase the precision of estimators. We propose a new chain ratio estimator of a finite population mean using two auxiliary variables and obtain mean square error (MSE) equations for proposed estimator. We find theoretical conditions that make proposed estimator more efficient than estimator of Abu-Dayyeh etc using two auxiliary variables.
