When the Average Lies

A billionaire walks into a bar and everyone gets rich on average

A billionaire walks into a bar, and on paper every customer just became a multimillionaire. Whose number lied?

You'll find out

  • How one guest can move an average
  • The number a billionaire can't budge
  • Why you have more legs than average

Why it matters

Pay, prices, grades, reviews: averages are everywhere. Knowing when one misleads stops a true number from fooling you.
