C)dfA
D)dfError

Question

Quizplus · Accepted Answer

The variation within groups is the variability between individual scores in each group, which is reflected in the within-group or error mean square (MSError). MSA reflects the variability between group means. dfA reflects the degrees of freedom for the factor or treatment effect, while dfError reflects the degrees of freedom for error or within-group variability. However, neither of them directly reflects the variation within groups.
