Question

mrs. valdez created a scatter plot that showed the number of days a student was absent compared to the students grade average in class. which statement best describes the association of the data shown in the scatter plot? student performance a. there is no association, since it has at least one outlier. b. there is a positive association based on the overall pattern. c. there is a negative association based on the overall pattern. d. there is no association, since there is a cluster towards the top.

Explanation:

In a scatter - plot, a positive association means as \(x\) (number of days absent) increases, \(y\) (grade average) also increases. A negative association means as \(x\) increases, \(y\) decreases.
Looking at the scatter - plot: as the number of days absent (\(x\)) increases, the grade average (\(y\)) decreases. For example, when \(x = 1\), \(y\approx95\); when \(x = 8\), \(y = 58\).

Answer:

C. There is a negative association based on the overall pattern.
