Explanation please

Which of the following describes the pattern of association for the scatter plot?

There is a positive linear association.
There is a positive nonlinear association.
There is a negative linear association.
There is a negative nonlinear association.

Answer 1

Positive nonlinear association, the graph does not show a constant increase of growth or look like a line but it does grow just not proportionately.

Answer 2

Answer: Positive Nonlinear Association

Explanation:

Take a look at the graph. From what we can see, it is going up. Hence, it's positive (meaning C and D are not the answer).

The way to tell between linear and nonlinear is the line. If you can perfectly fit all the points on a straight line, then it is linear. Clearly, you can't fit all the points on a singular straight line here, so it is nonlinear.
