The mean is a commonly employed descriptor of a set of numbers, and forms the basis for several related statistics. Evidence indicates many undergraduates do not possess a relational understanding of the mean concept (Pollatsek, Lima, and Well, 1981). Pollatsek postulated three types of knowledge are involved in understanding the mean: functional, computational, and analog knowledge. Many of the college students they interviewed did not appear to posses adequate functional and computational knowledge, while none showed behaviors which might suggest they possessed analog knowledge.
