In an ANOVA, the degrees of freedom for the between-groups variance is calculated as the number of groups minus one (4 groups - 1 = 3 degrees of freedom), and the degrees of freedom for the within-groups variance is calculated as the total number of observations minus the number of groups (40 participants - 4 groups = 36 degrees of freedom). Therefore, the correct way to read the degrees of freedom is "3 and 36 degrees of freedom."
