Interactive, Manipulative, The Mathenæum
It is easy to forget that “summary statistics” such as mean, range, deviation, correlation etc are only summaries. Anscombe's Quartet is an informative demonstration of the dangers of overlooking this fact. This activity uses 3 sets of values from the quartet, as well as supports student experimentation using their own data. Calculation of sum, mean, standard devation and plotting of points is included.
