    Abstract
    Cost, effort and time often become an obstacle to the course of study. Sampling one of the solutions. Two-stage sampling is often used to estimate the total population, stratification at the second stage (Neyman, 1938, Rao, 1973) or second phase (Binder, et.al, 2000) and for the estimation of regression (S¨arndal, et.al, 1992, chapter 9, Hidiroglou and S¨arndal, 1998). However, the sample variance estimator HT phase known generally very unstable and can result in negative values when units are selected with unequal probabilities. On the other hand, the variance estimator Sen-Yates-Grundy (SYG) is relatively stable and non-negative. Expansion of the two-stage sampling procedure can proceed to stage three.
     
    Biaya, tenaga dan waktu sering menjadi penghambat berlangsungnya penelitian. Penarikan sampel salah satu solusi. Penarikan sampel dua-tahap sering digunakan untuk memperkirakan total populasi, stratifikasi pada tahap kedua (Neyman, tahun 1938, Rao, 1973) atau kedua tahap (Binder, et.al, 2000) dan untuk estimasi regresi (S¨arndal, et.al, 1992, bab 9, Hidiroglou dan S¨arndal, 1998). Namun, varians estimator HT pada sampel fase umum dikenal sangat tidak stabil dan dapat menghasilkan nilai-nilai negatif ketika unit yang dipilih dengan probabilitas yang tidak sama. Pada sisi lain, varians estimator Sen-Yates-Grundy (SYG) relatif stabil dan non-negatif. Perluasan dari penarikan sampel dua tahap dapat dilanjutkan ke tahap tiga.
