Question

Look at this scatter plot.

A scatter plot is shown with 27 data points showing a strong negative relationship. The x-values of the data points extend from 0 to 10, and the y-values of the data points extend from 10 to 0.

Which of the following lines best fits the data?

A.
A U-shaped curve drawn on the scatter plot. The number of data points above the curve is 17 and the number below the curve is 8.

B.
A horizontal line is drawn on the scatter plot. The number of data points above the line and the number below the line are about equal.

C.
A downward sloping line is drawn on the scatter plot. The number of data points above the line and the number below the line are about equal.

D.
A downward sloping line is drawn on the scatter plot. Most of the data points are below the line.

Answer 1

C

A straight line with downward slope that has about half the points above and half below best matches a strong negative linear relationship.
