Coeficient = R^2. Measure of dispersion
Arrange from most ordered, to most disperse
Diagram 2, Diagram 1, Diagram 3, Diagram 4
Now arrange answers, from bigger to lower
1 , 0.89 , -0.09 , -0.65
Then ANSWERS ARE
DIAGRAM 2 ) Coefficient= 1
DIAGRAM 1 ) Coefficient = 0.89
DIAGRAM 3) Coefficient = -0.09
DIAGRAM 4) Coefficient = -0.65
