Penaksir Dual Ratio-Cum-Product Untuk Rata-Rata Populasi Pada Sampling Acak Sederhana
ABSTRACT
This final project discusses three estimators for the population mean in simple
random sampling are dual ratio estimator, dual product estimator and dual ratiocum-
product estimator. These estimators are biased estimators. The mean square
error for each estimator is evaluated and compared to obtain the most efficient
one. This comparison shows that the dual ratio-cum-product estimator is more
efficient than the dual ratio estimator and dual product estimator.
Keywords: dual ratio estimator, dual product estimator, dual ratio-cum-product
