Question 8 • TX-Advanced Quantitative Reasoning

What is the purpose of a regression line?

Answer

A

to connect all the points in a scatterplot

B

to show the general tendency of the points in a scatterplot

C

to provide a scale for the x-coordinates of the points in a scatterplot

D

to provide a scale for the y-coordinates of the points in a scatterplot

Explanation

A regression line summarizes the relationship between two variables by showing the overall trend in a scatterplot. It does not connect every point, and it is not a scale for either axis. So the correct choice is “to show the general tendency of the points in a scatterplot.”
