Review the scatter plot of hours students studied for a test and their results.

This question tests interpretation of scatter plots and correlation. In the graph, the horizontal axis represents hours studied, and the vertical axis represents test scores. As the points move from left to right (indicating more hours studied), the points also tend to move upward (indicating higher test scores). This shows a positive relationship between the two variables. While not every point follows a perfect line, the overall trend clearly indicates that students who studied more hours generally achieved higher test scores. Option B correctly describes this positive correlation. Option A is incorrect because scores are not highest when no studying occurs. Option C is incorrect because there is a visible relationship. Option D describes a negative relationship, which is not shown. On the NEX exam, scatter plots are often used to test understanding of trends rather than exact values, so identifying the overall direction of the data is key.
