Question 46 of 60

46) A teacher sets up a reward system for her elementary school students. At the end of each day, she gives a sticker to each student who showed up on time that morning. At the end of each week, she gives a sticker to any student who got above a 90% on three quizzes in a row. After months of this regimen, she finds that performance on the quizzes has increased significantly but that tardiness has only decreased slightly. Which of the following best explains the teacher’s observation?
