Using cooperative learning methods, this activity introduces distributions for univariate data, emphasizing how distributions help us visualize central tendencies and variability. Students collect real data on head circumference and hand span, then describe the distributions in terms of shape, center, and spread. The activity moves from informal to more technically appropriate descriptions of distributions.
