Penaksiran Variansi Populasi Menggunakan Variabel Bantu Kombinasi Koefisien Kurtosis Dan Median Pada Sampling Acak Sederhana
This final project discusses three estimators for estimating population variance
in simple random sampling without replacement using coefficient kurtosis,
median and combination of coefficient kurtosis and median. The three
estimators are bias estimators. To obtained an efficient estimators that is by
determining the smallest mean square error (MSE) using Taylor series
approximation. The efficient estimators is the one with the minimum MSE
determined by comparing each type of the estimators. From the result
obtained that the MSE using combination of coefficient kurtosis and median
are the smallest MSE.
Keywords: Simple random sampling, kurtosis, median, Taylor series, bias,
