Modifikasi Penaksir Rasio Untuk Menaksir Rata-Rata Populasi Menggunakan Kuartil Dan Rata-Rata Desil Pada Variabel Tambahan
The ratio estimators studied here are ratio estimators for population mean on
simple random sampling by using the auxiliary information of second quartile,
quartile deviation and decile mean. Each estimator is biased estimator.
Furthermore, the mean square error (MSE) from each estimator is determined
so that an efficient estimator can be obtained by comparing MSE from each
estimator with the simple ratio estimator. Then it is obtained that estimators
using the second quartile and the decile mean are more efficient than others.
Keywords: Ratio estimator, simple random sampling, second quartile, quartile
