Experimental Design
Apprentices at a local bank are randomly put into teams of 3-4 people. They elect a person. In the preparation phase, they decide on a team name and plan their approach. In the memory phase, they are given a map and asked to memorize as a team building names and locations without taking notes or talking to each other. In the decision phase, the map is taken away and participants are given 20 questions about the map. The team with most correct answers wins a monetary prize.
