Question

Identify the correlation coefficient that best matches each scatterplot

Answer 1

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
