In the past few years, considerable attention has been given to extropy measure. The and weighted of ranked set sampling were studied by several authors. general some results related it are introduced in this paper. We provide sampling. also characterization results, stochastic comparison monotone properties extropy.

Multistage pair ranked set sampling (MSPRSS) is a rank-based design that improves statistical inference with respect to simple random of the same size. It applicable when exact measurement difficult, but judgment raking potential sample units can be done fairly accurately and easily. The ranking usually performed based on personal or concomitant variable, need not totally free errors. This arti...

Ranked set sampling (RSS) assumed perfect ranking i.e. there will be no errors in ranking the units with respect to the variable of interest. In fact for most practical applications, it is not easy to rank the units without errors in ranking. There will be a loss in efficiency, i.e. RSS will give a larger variance due to the errors in ranking the units. To reduce the errors in ranking in estima...
