Abstract:In this paper,efficiency of the estimator of population mean under the circumstance of distinct units and whole sample based on Eichhorn and Hayre model was studied by using simple random sampling with replacement.The results of numerical simulation showed that the precision of the distinct units was higher than that of whole sample.
Keywords:distinct units  whole sample  efficiency comparison  numerical simulation
