- Acceptable quality level
- The maximum percentage or proportion of variant units in a lot or batch that, for the purposes of acceptance sampling, can be considered satisfactory as a process average.
- Analysis of Variance (ANOVA)
- A technique which subdivides the total variation of a set of data into meaningful component parts associated with specific sources of variation for the purpose of testing some hypothesis on the parameters of the model or estimating variance components.
- Assignable cause
- A factor which contributes to variation and which is feasible to detect and identify.
- Average Outgoing Quality (AOQ)
- The expected quality of outgoing product following the use of an acceptance sampling plan for a given value of incoming product quality.
- Average Outgoing Quality Limit (AOQL)
- For a given acceptance sampling plan, the maximum AOQ over all possible levels of incoming quality.

- Chance causes
- Factors, generally numerous and individually of relatively small importance, which contribute to variation, but which are not feasible to detect or identify.
- Coefficient of determination
- A measure of the part of the variance for one variable that can be explained by its linear relationship with a second variable. Designated by r 2 or r 2.
- Coefficient of multiple ...
