The ‘‘Lady Tasting Tea’’ is a famous real story in the history of the development of statistics in the 20th century, related to R.A. Fisher, one of the greatest statisticians and founders of modern statistics. This story took place in Cambridge, England, in the late 1920s. A group of university dons, their wives, and some guests were sitting around an outdoor table for afternoon tea. A lady, a colleague of Fisher’s, claimed to be able to judge whether tea or milk was poured in the cup first. Fisher designed a classic experiment to test the lady’s claim. According to Fisher’s daughter, this story is real. Here’s an account of the seemingly trivial event that had the most profound impact on the history of modern statistics (Box, 1978). In the second chapter of R.A. Fisher’s text The Design of Experiments (1935), Fisher described the experiment and the test of significance. The lady was given 8 cups of tea, in 4 of which tea was poured first and in 4 of which milk was poured first, and
was told to guess which 4 had milk added first. Fisher’s exact test, i.e., a permutation test based on an exact hypergeometric distribu-tion was used to test the lady’s claim.
