Where in the class room do you usually sit? Among us teachers, it is believed that the better students generally sit closer to the front. But is that true? I decided to test that hypothesis.
At the beginning of the semester, I took a photograph of the students in their seats in the lecture hall. At the end of the semester, after I have finished grading, I plot a graph of the overall performance of the students (vertical axis) against the distance between their seats and the lecturer (horizontal exis). Indeed, there is a noticeable negative correlation there. The closer they are to the lecturer, the better their perfomance tends to be.
