This resource is based on real experiments in the 1930s by Karl Zener who designed the cards used (now known as Zener Cards). The purpose is to test for clairvoyance. There are 5 different types of card and 5 of each design giving a deck of 25.
Students are shown the back of a card and are asked to choose what they think the card is. The resource keeps a tally and presents a frequency at the end. The frequency is only given at the end to emulate the normal use of tally charts.
Note that the card sequence is pre-determined, so this is best done as a one-off experiment.
