Which of the following samples provides the most evidence that the amount of time spent studying for an exam and the grade on the exam are positively correlated?

Four side-by-side scatterplots compare the amount of time spent on studying for an exam and the grades on the exam. The scatterplots are labeled as: A, B, C, and D.  In A, the cluster of dots is plotted increasing toward the right. The dots are spaced out at the bottom left end of the cluster. In B, the cluster of dots is decreasing toward the right. The dots are spaced out at the bottom right end of the cluster. In C, the cluster of dots is plotted throughout the graph. The space between the dots is approximately uniform throughout the cluster. In D, the cluster of dots is plotted increasing toward the right. The dots are spaced out at the top right end of the cluster.

▸ Sample A

▸ Sample B

▸ Sample C

▸ Sample D
