Consider the following news headline, “Cigarette Smokers Make Lower College Grades Than Nonsmokers.” The article goes on to say that researchers at a university collected information on the rate of cigarette smoking (total number of cigarettes smoked in a one-month period) and the college student’s current GPA for completed college courses. They found that those with higher levels of cigarette use had lower GPAs, and vice versa. What can you rightfully conclude from this? Why? Be specific about what this kind of information may indicate and mean.
