This deck of 108 cards is designed with face values that approximately follow the normal distribution. The face values range from 1 to 12. They have a median of 6.5 and a standard deviation of 2. There are 6 suits of 18 cards each in the deck, with pips in the shape of different leaves.
The deck can therefore be used to play many traditional card games that rely on numbered faces and as a manipulative for lessons on probability and statistics.
