Abstract
in stratified sampling in terms of the precision of the population mean base on the inherent characteristics of the population. These conflicting views were analyzed using Cochran data (1977, p.211) [1]. When the population units are ordered, variance of systematic sampling for all possible
systematic samples provides equal, non-negative and most precise estimates for all the variance
functions considered i.e. 1 ( sy ) 2 ( sy ) 3 ( sy ) V y = V y = V y , unlike when a single systematic sample is used and when variance of simple random sampling is used to estimate selected systematic samples
