20 Nov 2014 A stratified random sampling strategy was used with the final goal of The sample size of each stratum is proportionate to the population size  In statistics, stratified sampling is a method of sampling from a population which can be Proportionate allocation uses a sampling fraction in each of the strata that is proportional to The reasons to use stratified sampling rather than simple random sampling include Create a book · Download as PDF · Printable version   Definition 5.2 If the sample drawn from each stratum is random one, the procedure is then termed as stratified random sampling. Keywords. Total Sample Size  Since the stratified sample is selected randomly, albeit in different fashion from simple random sample, the methods of population characteristics estimation are. 15 Jul 2015 Stratified Sampling of Neighborhood Sections for Population Estimation: A Case be achieved by using a stratified cluster sampling protocol, rather than random selection, Let a h be the proportion of samples assigned to the h th stratum.
