A negative correlation coefficient indicates an inverse relationship between the two variables. As one variable (hours of strenuous exercise) increases, the other variable (body mass) decreases. A coefficient value of -.74 indicates a strong negative correlation, implying that as hours of strenuous exercise per week increase, body mass decreases significantly.
