Exercise 27-9: Proximity to the Teacher Recall from Exercise 5-23 the idea of studying whether students who sit closer to the teacher tend to have higher quiz scores than students who sit farther away from the teacher. Suppose you measure distance from the teacher and average quiz score for a group of students. Explain how you know each of the following statements is in error: a. The correlation between distance and quiz average is -1.8. b. The correlation between distance and quiz average is -.8, and the correlation between quiz average and distance is -.4. c. The correlation is -.8, so there is no association between distance and quiz average. d. The correlation between quiz average and gender is -.8. e. The correlation between distance and quiz average is -.8, so students who sit farther away tend to score higher. f. The correlation between distance and quiz average is -.8, so sitting closer to the teacher must cause students to score higher on quizzes
