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 samplesenPrecision, Systematic sampling, Stratified systematic sampling, Systematic random estimatorArticle
