Luck of the Draw

Make a set of cards like those shown below. Shuffle the cards and divide them equally.

Each partner arranges his or her cards so that the numbers are in numerical order and then finds the interquartile range of the numbers on his or her cards. The partner with the greater interquartile range wins the round. Play several rounds, shuffling the cards each time.
