Question

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

Explanation:

Step1: Recall residual plot property

For a good - fit regression line, the residuals should be randomly scattered around the horizontal axis.

Step2: Analyze Data set A

In Data set A, the residuals show a pattern (a curve - like trend), which indicates a non - linear relationship and a poor fit.

Step3: Analyze Data set B

In Data set B, the residuals are randomly scattered around the horizontal axis, which is a sign of a good fit for the regression line.

Step4: Analyze Data set C

In Data set C, the residuals do not show a random pattern but seem to be clustered in certain areas, indicating a poor fit.

Answer:

B. Data set B
