Gage repeatability and reproducibility studies determine how much of your observed process variation is due to measurement system variation. Use Gage R&R Study (Expanded) when you need to include more factors than Operator and Part, have fixed factors, a mixture of crossed and nested factors, or an unbalanced design. You can have a maximum of eight factors in addition to Part and Operator. All factors can be fixed or random, and crossed or nested. The design can be balanced or unbalanced.
Gage R&R Study (Expanded) uses the ANOVA method for assessing repeatability and reproducibility. You can also add other main and interaction effects to Reproducibility in addition to, or instead of, Operator and Operator by Part. Optionally, you can specify terms in addition to Part to calculate part-to-part variation.

Part numbers: Enter the column containing the part names or numbers.
Operators: Enter the column containing operator names or numbers (optional).
Measurement data: Enter the column containing the observed measurements.
Additional factors: Enter a maximum of 8 columns containing factor level names or numbers (optional).
Fixed factors: Specify parts, operators, and/or factors in Additional factors that are fixed factors (optional). By default, factors are assumed to be random factors.
Nesting (e.g., Parts(Operators) ... Parts nested in Operators): Specify nesting among the factors. See Specifying nesting for more information.
