HELP ME SO I DON’T FAIL! A regression line was calculated for three similar data sets (A, B, and C) that measure the height of a

plant (in inches) over time (in days). The residual plots for each set are shown. Based on the residuals, which data set is best fit by the regression line?
A. Data set A

B. Data set B

C. Data set C

Answer:

A) Data set A

Step-by-step explanation:

Residuals describe how far each point is from the regression line. The farther each point is from the line, the worse the fit; the closer each point is to the line, the better the fit.

Graph B has points that are not tightly centered around a line. This is not a good fit.

Graph C has a U-shape; it is not a good fit.

Graph A, however, shows us that all of the points are tightly centered around a line; this is a good fit.
