PROGRESS Multi-disciplinary Research Journal, 2(1), 43-50.2026-7096http://hdl.handle.net/10628/405The standard deviation of a population (of size N ) is a measure of the spread of the population observations about the mean. A population may be clustered and the standard deviation of each cluster calculated. This paper looked at how the mean of the standard deviations of the clusters of a population of random numbers relate to the standard deviation of the population as the size of the clusters increased. We assumed that all clusters have the same size.enStandard deviation of populationPopulation clustersSequence of means of standard deviationsShort-cut estimatesProximityCluster sizeEstimation of standard deviationRandomly generated numbersNon-monotonic convergenceConvergence simulationArticle
