Assignment 12 (Honors)
Read the article "Your parents are correct, scholars report: Studying pays off."
The authors of the study claim that three causal relationships were demonstrated in their study:
1) Having a roommate
who brought a video-game console to college decreased one's studying time.
2) Reduced study time contributed to lower grades.
3) Having a roommate who brought a video-game console to college contributed to one's lower grades.
Which, if any, of the three causal claims were supported by the study? Explain.
(Optional -- Here
is the actual research article, "The
causal effect of studying on academic performance," if you want to
see it. Caution: It is 42 pages if you print it out!)
