which scatter plot shows a positive association?

Brief Explanations:

In a scatter - plot with a positive association, as the value of the x - variable increases, the value of the y - variable also tends to increase. The first plot shows a negative association (y decreases as x increases), the second plot shows a negative association too, the third plot has no clear linear association, and the fourth plot shows that as x increases, y increases.

Answer:

The scatter - plot in the bottom - right corner shows a positive association.
