Question

Quizplus · Accepted Answer

The degrees of freedom for factor A in a two-factor between-subjects ANOVA is equal to the number of levels of factor A minus 1 (a-1). This is because the number of levels of factor A determines the number of independent groups being compared, and the degrees of freedom correspond to the number of independent pieces of information available for estimating the population parameter of interest (the mean difference between levels of factor A).
