    Abstract :

    Ranked Set Sampling was proposed by McIntire (1951) in order to reduce measurement cost and still obtain an efficient estimator of the population mean. The purpose of this paper is to look in to some of the ranking error models proposed in the literature and evaluate their impact in the gain in precision of ranked set sampling over simple random sampling. This paper reviews some of the models suggested by researchers in the literature on ranked set sampling. Subsequent studies will be undertaken for developing new and hopefully better models for ranking errors in ranked set sampling.
