  • A pun to familiarize students with Anscombe's Quartet - the group of 4 data sets with the same means, standard deviations, correlations, and regression lines for X and Y that were produced by British statistician Frank Anscombe in a 1973 paper in the American Statistician. The joke was written in 2016 by Larry Lesser from The University of Texas at El Paso. This joke should be used in a written rather than oral presentation since students will not "get" the joke if they have never heard of Anscombe's Quartet - the value for teaching coming from having them look it up.
