Each of these graphs of residuals is from the same set of data using different lines to fit the data. Which graph is most likely to represent the residuals from the best fit line? Be prepared to show your reasoning.
Graph A
Graph B
Graph C
Graph D
Compare your answer:
Graph A is most likely to represent the residuals from the best fit line. The residuals seem well spaced on either side of the -axis without an obvious pattern, and all of the residuals are close to 0.
