Abstract: | We adapt the ratio estimation using ranked set sampling, suggested by Samawi and Muttlak (Biometr J 38:753–764, 1996), to
the ratio estimator for the population mean, based on Prasad (Commun Stat Theory Methods 18:379–392, 1989), in simple random
sampling. Theoretically, we show that the proposed ratio estimator for the population mean is more efficient than the ratio
estimator, in Prasad (1989), in all conditions. In addition, we support this theoretical result with the aid of a numerical
example.
