    PENAKSIR RASIO UNTUK RATA-RATA POPULASI PADA SAMPLING ACAK SEDERHANA MENGGUNAKAN KOEFISIEN VARIASI DAN MEDIAN
    (2014-03-25) Rahmadani, Riski; Adnan, Arisman; Sirait, Haposan
    This paper discusses three ratio estimators for the population mean in simple random sampling using coefficient of variation and median of an auxiliary variable, which is a review from the article of Subramani and Kumarapandiyan. All estimators are biased, then their mean square errors (MSE) are determined. Furthermore, the mean square errors are compared to show which estimator is the most efficient estimator. This paper reveals that the estimator using coefficient of variation and the median has the smallest mean square error (MSE)
