New to Quality? Let ASQ's Quality Resources help. This week's feature is Attribute & Variable Sampling Plans and Inspection Procedures.
Attribute sampling is defined as the method of measuring quality that consists of noting the presence (or absence) of some characteristic (attribute) in each of the units under consideration and counting how many units do (or do not) possess it. However, sampling systems are not restricted to attributes. They may be composed of variable plans as well. The difference lies with the measurement data utilized.
