Tipe Penaksir Untuk Rasio Rata-Rata Populasi Pada Sampling Berstrata
This final project discusses ratio type estimators of two population means using
the auxiliary information in stratified sampling, i.e. ratio type estimator (ˆR1st)
and modified ratio type estimator (ˆR2st) as discussed by Jan et al. [Indian
Stream Research Journal 4 (2014), 1-6]. The two ratio type estimators are
biased estimators, then the mean square error (MSE) of each ratio type
estimator is determined. Furthermore, the proper condition is shown to
determine which one is more efficient estimator.
Keywords: Ratio estimator, auxiliary information, stratified sampling, bias
