Question

● as the number of absences increases, the final grade tends to decrease
● as the number of absences increases, the final grade tends to increase
● there is no relationship between absences and final grade
● the number of absences is not a good predictor of the final grade

Explanation:

Negative association means as one variable increases, the other tends to decrease. Here, more absences (one variable) correlate with lower final grades (the other variable).

Answer:
