The F statistic for the first main effect in a 3 × 5 ANOVA with replication can be found using the F-distribution table. With 2 degrees of freedom for the numerator (3 levels - 1) and a certain number of degrees of freedom for the denominator (depending on the total number of observations), the critical value at the .05 level is approximately 3.68.
