Question

indicate whether each of the following plots show a positive association, a negative association, or
(a)
the plot shows a negative linear association.
the plot shows a negative nonlinear association.
the plot shows a positive linear association.
the plot shows a positive nonlinear association.
the plot shows no association.
(b)
the plot shows a negative linear association.
the plot shows a negative nonlinear association.
the plot shows a positive linear association.
the plot shows a positive nonlinear association.
the plot shows no association.

Explanation:

For (a): The scatter plot points follow an upward, straight-like trend: as one variable increases, the other increases linearly.
For (b): The scatter plot points are randomly distributed with no clear upward/downward or curved trend, so there is no association between the variables.
