8. Using multiple regression, researchers found that greater levels of sibling aggression predicted worse mental health in children, even when controlling for the parents' education level and the child's age, gender, and ethnicity. Can the researchers conclude that sibling aggression causes worse mental health? a. Yes, because covariance, temporal precedence, and internal validity have all been established. b. No, because other variables not measured by the researchers could explain the relationship between sibling aggression and mental health. No, because temporal precedence has not necessarily been established. d. both (b) and (c) С.
