Aubrey investigates the relationship between exam timing and average scores using data from the previous year. The data is plotted on a scatter plot to identify any trends. The analysis involves plotting periods on the horizontal axis and average scores on the vertical axis. Despite plotting various data points, no clear trend is observed, leading to a conclusion that the timing of exams may not significantly affect average scores.
