The present manuscript pertains to an efficient ratio type predictive estimator for estimating finite population mean using the information on median of the study variable. Mathematical expressions for the bias and mean squared error (MSE) of the proposed predictive estimator have been obtained upto the first order of approximation. A theoretical efficiency comparison of the proposed estimator has been made with the Singh et al.(2014) and Yadav and Mishra (2015) estimators under predictive modelling approach. Theoretical findings are validated through the numerical study, and it has been found that proposed estimator performs better than the existing estimators.
