The program contains descriptive information on how to use it. Sample sizes are determined for descriptive surveys based on analysis of the precision (standard errors) of estimates of interest (e.g., estimates of overall characteristics (totals, means, proportions) of a population or subpopulations of interest). Sample sizes are determined for analytical surveys based on statistical power analysis. For additional information on using statistical power analysis to determine sample size for analytical surveys, see the following article:
