This website supports the application of two kinds of statistical sampling plans:
bulletAcceptance sampling plans to detect off-grade product and processes.
bulletEstimation sampling plans for audits and surveys to attain precise estimates.
The main statistical tools that we use are:
bulletoc-curves to design acceptance sampling plans with known probabilities. 
bulletmargin-of-error for precise estimation and measurement.
bulletsoftware to perform all statistical and design calculations.
The website contains these three areas:  See the link-buttons at the top of each page.
