A scatter plot would best display the correlation between the number of problems completed on the homework assignment and success on the exam. The x-axis would represent the number of problems completed and the y-axis would represent the exam score. Each student's data point would be plotted on the scatter plot, and any trends or correlations could easily be seen.
