ANAVAR method
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:
