Mathalicious: Biggest Loser (Classic)

How should the winner of The Biggest Loser be chosen?

In the reality game show The Biggest Loser, contestants compete for cash prizes based on who can lose the most weight. But how should we define “the most weight,” and is The Biggest Loser scored fairly?

In this lesson, students use percent change to compare absolute and relative weight loss for several contestants and examine historical data to determine which method produces the fairer game.
