ANSI Z1.9 (Acceptance Sampling for Variables)

WebAug 6, 2024 · Variable sampling is about checking “how much”, “how good”, or “how bad”. Examples Let’s say you need to provide the average adult male and female height by country. Obviously you cannot measure the height of every adult in every country. WebJan 8, 2016 · The alternative approach is acceptance sampling by variables, in which you use a measurable characteristic to evaluate the sampled items. Doing it by attributes is easier, but sampling by variables requires smaller sample sizes.
