Abstract
Estimators discussedare combination of ratio estimatorsin ranked set sampling using
coefficient of variation and coefficient of kurtosis. Each estimator is biased
estimatorand the mean square errors are determined. Estimator with thesmallest mean
square error is an efficient estimator.An example is given at theend of discusssion
