A college professor has received comments on his teaching evaluations that his handwriting on the board is too small in large classrooms. He wants to determine if this is affecting his students' grades, so one semester he selects a random sample of his students and takes note of whether each student in this sample is sitting in the front half or the back half of the classroom, then compares the course averages of these two groups at the end of the semester. He discovered that students who sit in the front half of the room have significantly higher final course averages. Which of the following is the most appropriate conclusion based on the results of this study? (A) Where a student chooses to sit in the classroom has no effect on how well they do in the course. (B) Students who sit at the back of the classroom do not perform as well as those who sit at the front because they cannot see what is written on the board. (C) Students who sit at the back of the classroom do not perform as well as those who sit at the front because they are texting and otherwise inattentive. (D) Students who sit at the front of the classroom are more serious students. (E) None of the above conclusions are appropriate.
