PENAKSIR RASIO YANG EFISIEN UNTUK RATA-RATA POPULASI DENGAN MENGGUNAKAN DESIL PADA SAMPLING ACAK SEDERHANA

Abstract

This paper studies three ratio estimators in simple random sampling by using the second decile, fifth decile and the eighth decile. This three ratio estimators are biased estimators. Their mean square errors are compared to find the most efficient estimator. The smallest mean square error of them is the most efficient estimator. A numerical example is given to explain the problem discussed.
