E.            Measurement system analysis
Calculate, analyze, and interpret measurement system capability using repeatability and reproducibility (GR&R), measurement correlation, bias, linearity, percent agreement, and precision/tolerance (P/T). (Evaluate)

Repeatable and reproducible (GR&R)  - assuming that gage accuracy and sensitivity are assured, it is often desirable to determine the variance components of a gage measuring system.

Measurement correlation – comparison of the measurement values from one system with the corresponding values reported by one or more different measurement systems.

Bias – the difference between the output of the measurement system and the true value.

Linearity – is found by obtaining reference part measurement values throughout the operating range of the instrument, and plotting the bias against the reference values.

Percent agreement -

Precision/tolerance (P/T) – the ratio between the estimated measurement error (precision) and the tolerance of the characteristic being measured.
