This paper suggests difference-cum-ratio and exponential type estimators of population mean using first or third quartiles and mean of auxiliary variable under median ranked set sampling scheme and we have
extended our study in double sampling scheme when the population parameters are unknown. The bias and mean square error of estimators
are derived by theoretically both of sampling designs. Empirical studies have been done to demonstrate the efficiency of proposed estimators
over the existing estimators. We have found that difference-cum-ratio
estimator is always more efficient than regression estimator and both
of the estimators are considerable efficient than existing estimators.
