Scatter Plot Graph: How Correlated?

\text{True or False}

===

Scatter plot with points: (0,0), (1,4), (2.5,6.25), (2,6), (3,6), (4,4), (5,0), (0.5,2.25), (4.5,2.25), (0.25, 1.188), (4.75,1.188), (1.5,5.25), and (3.5,5.25).

A ball is tossed into the air and it's height is measured at different times. Even though it maps perfectly to a quadratic function, we cannot say it's a perfect correlation because the points don't fit on a linear line.
