Age-guessing data from our classroom demonstration (as appearing in the Gelman and Nolan book): Errors in age guesses from a class of eighth graders, as displayed on the blackboard. For the first two cards, we wrote the guessed and true ages, then we switched to writing the true age and the estimation error for each group. At the end, the groups were compared using the average of the absolute values of the errors. The sexes and group sizes are shown because one of the students in the class commented that the girls' guesses were, on average, more accurate.
