Consider the two scatter charts and related trendline and regression statistics shown for Anscombe's data sets in the figures below. The estimated regression equations and related R-squares for both data sets are identical. - Does fitting a line to the data appear to be a wise choice for both data sets? Explain your answer. - What would be a more appropriate regression equation to fit Anscombe's Data Set 2?
