Resumo Inglês:
We consider the modified ratio estimator proposed by Swain (2013). It is an extension of the classic ratio estimator. The objective of this paper is developing the ranked set counterpart of the new estimator, developed by Swain (2013). We derived a new ranked set sampling ratio estimator. For illustrating the behavior of the proposal a comparison of their approximate mean squared error was developed. The proposed procedure appeared as more accurate. Empirical studies give an insight on the magnitude of the efficiency of the estimator developed.
