When numbers and sounds are not what they seem

Can you solve it? Dotty data and silly sentences

This article presents three puzzles about how things can seem different from how they really are. These puzzles involve numbers and language.

The first puzzle is about a school with two classes. After the year, students are given grades. In the first year, the middle student gets a C. In the second year, a new teaching plan is used. This time, the middle student gets a D. The challenge is to think of a situation where the new plan actually made every student's grades better, even though the middle grade went down.

The second puzzle looks at two polls about a government policy. Both polls, each with 125 people, suggest the policy is more popular with men. However, the data shows something surprising. Smith Surveys found 84% of men supported the policy and 80% of women did. Jones Polls found 22% of men supported it and 20% of women did. You need to figure out if the policy is actually more popular with men or women based on the combined information.

The third puzzle introduces 'Anguish Languish,' an invented language. It uses English words that sound similar to create nonsense sentences that, when spoken, sound like a different, normal sentence. For example, 'Ones her punnet I’m, inner smell vial itch they’re lift a misty verse buoy culled Pitter' sounds like 'Once upon a time in a small village there lived a mischievous boy called Peter.' The article offers a prize for the funniest Anguish Languish sentence.

The book mentioned, 'You Don’t Know What You’re Missing,' explores how hidden information can change our understanding of the world. This includes how survey results can be changed before we see them, and the difference between how words sound and what they mean.

Discussion Questions

  2. What makes the second puzzle tricky, and how can you find the correct answer?
  3. Can you explain how 'Anguish Languish' works with another example?
