Which associations best describe the scatter plot? select each correct answer. (a) linear association, (b) positive association, (c) negative association, (d) nonlinear association

The correct answer is (C) Negative association

Explanation:

A scatter plot is a type of graphic used to depict the relationship between two variables or factors using points in a vertical and horizontal axis. In this context, negative association or correlation occurs when the two variables do not increase or decrease together but one increases and the other decreases or vice-versa. This occurs in the scatter plot presented because the number of individuals infected (y-axis) decreases over time (x-axis). This means the first variable decreases while the second variable increases and therefore there is a negative association.

d. you cannot tell because there are no values shown.
