In 1973, the statistician Francis Anscombe devised a fascinating demonstration showing why data should always be plotted before it is analyzed. The demonstration consisted of four data sets that had almost identical statistical properties. By this measure they are essentially the same. But when plotted, the data sets look entirely different. Anscombe's quartet, as it has become known, shows how good graphics allow people to analyze data in a different way, to think and talk about it on another level. Most scientists recognize the importance of good graphics for communicating complex ideas.
