To calculate the GRR and Cpc by using the ANAVAR method, the statistical analyses of the Fisher test are used:

Source variability | Sum of squares | Degree of freedom | Average of squares | F statistic |
---|---|---|---|---|

Operator | SSA | a-1 | ||

Parts | SSB | b-1 | ||

Interaction (Operator/part) | SSAB | (a-1)(b-1) | ||

Instrument | SSE | ab(n-1) | ||

Total | TSS | N-1 |

The repeatability of the measurement system is given by:

The reproducibility of the measurement system is given by:

The interaction is given by:

The variability of the measurement system is given by
