F-Test P-Value Calculator (ANOVA)

Calculate the p-value for F-tests (e.g., ANOVA) based on the F-statistic and degrees of freedom.

Back to P-value Calculator

The probability threshold (alpha) for rejecting the null hypothesis. Common values are 0.05 or 0.01.

In ANOVA: k − 1 (number of groups minus 1). In regression: number of predictors.

In ANOVA: N − k (total observations minus number of groups). In regression: n − p − 1.

Test Formula
F=MSbetweenMSwithinF = \frac{MS_{between}}{MS_{within}}
