The lady tasting tea experiment( Fisher, 1966) came about when a lady claimed that she could tell if milk had been poured into the cup before the tea was poured in. Ronald A fisher- then conducted an experiment so that the lady could prove this claim. 8 cups of tea were prepared but 4 with tea poured in first and 4 with milk poured in first before the tea.
