Quizplus · Accepted Answer

The best choice for a quantitative index that measures the degree of relationship between two variables (in this case, the first test score and the final exam score) is the correlation coefficient. It shows the strength and direction of the relationship, indicating if the two variables are positively, negatively, or not related. Therefore, option D, correlation coefficient, is the appropriate choice in this scenario.
