We have all heard stories of child prodigies who enroll in college programs for advanced degrees at an early age. We would say that there these people are above average in intelligence, but what does this mean? How do we compare individuals or sets of data, and how do we declare one to be "better than another"? See how Violet talks to Charlie Brown in the following Peanuts cartoon.

"My dad is better than your dad! Na, na, na-na na!" Do you suppose that Violet's dad bowled better on Monday nights (185 avg.) than on Thursday nights (170 avg.)? Don't be too hasty to say yes.
