11. Between-groups degrees of freedom is calculated by: Oa. subtracting 1 from the total number of subjects in the study. Ob. subtracting 1 from the total number of groups in the study. O subtracting 1 from the number of subjects within each group and then adding those numbers C. together. Od. multiplying the number of subjects by the number of conditions in the study and then subtracting 1. 12. If an F statistic is negative, which of these is true? Oa. There has been a calculation error. Ob. The difference among the group means is greater than what would have occurred by chance. Oc. The difference among the group means is less than what would have occurred by chance. Od. The within-groups variance exceeds the between-groups variance.
