In this discussion, explain why you think this would be a good study or not. If you think it is not a good study, how would you improve it? Why do we have to be careful when reading research in the news?  Can you recall any correlations reported recently in the news? (Hint: a common example correlates some variable with various aspects of health). Was the correlation positive or negative? What are the various possible causal relationships related to this correlation? What can you conclude about reading research that is NOT in a peer-reviewed scientific journal?
