Anscombe’s Quartet: Graphs Can Reveal

Abstract

We look at Anscombe's, (Am Stat 27(1):17-21, 1973) data which is one of the datasets that come with the R software. We compute different linear regressions of Anscombe's four sets of data-they give us the same results. When we look at the scatterplots corresponding to Anscombe's four sets of data we see that they are very different.
