About the calculation
Crossed ANOVA model with interaction. Strictly educational; it does not qualify the measurement system.
Calculations run locally in the browser. Statistical distributions and functions use jStat 1.9.6; values are rounded only for display. For method selection, conditions of use and interpretation criteria, see the “Sources and methodological alignment” section above and any customer-specific requirements.
