Abstract
The present paper is devoted to the development of ranked set sampling alternative to primals and duals of ratio estimators. A new class of ratio estimators is determined. It contains a subclass where the classic ratio estimator and some transformation of it belong. The ranked set sampling counterparts developed also belong to it.
Keywords: Ranked set sampling, mean squared error, extreme values
