Hidden properties in the main sampling techniques
About this article
Keywords:
Correlation Coefficient; Ordered Population; Periodic Population; Random Sampling Techniques Similar within; Similar Among.Abstract
Several important and hidden properties in the main sampling techniques, Simple, Stratified, Cluster and Systematic random samplings, are highlighted. A new result about Pearson correlation coefficient of all pairs of the values of the variable of interest for the population elements is explored. The highlighting of these properties may have a real contribution to educational statistics.
