10.CE.1(b)

Suppose that every student in your class scores 10 points lower on the final exam than on the midterm exam. What would the value of the correlation coefficient between the two exam scores equal?

r = 1. As midterm scores increase so do final exam scores and every final exam score is the same amount lower than the midterm score.

r = 0. As midterm scores increase, final exam scores do not change much and every final exam score does not changes as the midterm score increases or decreases.
