In "Longshot," a man is murdered at a horse racetrack after he wins a large sum of money. The FBI shows Charlie the man's notebook that contains a lot of horse racing data and equations. Some of these equations involve the harmonic mean. The harmonic mean is one of several methods of calculating an average.
In this activity, students will learn about three types of means and how each of them is used.
