Decline in math SAT scores. A New York Times article reported that average math SAT scores for the high school class of 2007 dropped 3 points compared with scores in 2006. Officials of the College Board, the nonprofit organization that administers the SAT, suggested that increased numbers of students taking the SAT had contributed to the decline in scores. “The larger the population you get that takes the exam, it obviously knocks down the scores,” said Gaston Caperton, the president of the College Board. Is this conclusion the result of an experiment? Why or why not? What are the explanatory and response variables?
