George Gallup

In the famous 1936 U.S. election poll fiasco, whose smaller, scientifically sampled poll beat the Literary Digest's 2-million-response survey?

The Literary Digest's huge sample was badly biased toward wealthier households, while Gallup's smaller, careful sample got it right.

about plus/minus 3%

For a poll of about 1,000 people, what is the typical margin of error?

Questions

How does SurveyBank.com work?

Each question asks you to guess a real number about surveys, polling, and public-opinion research. After you answer you see how everyone else guessed, then the real figure and where it comes from.

How is the daily round scored?

Four stats and one opinion poll. A correct guess earns 100 points plus up to 50 for speed, with a combo bonus for answers in a row. The range next to the right answer earns 40. Opinion polls earn 25 for having your say, and nailing every stat adds 150.

Where do the numbers come from?

Every stat links to its source, such as government statistics agencies, research organizations and industry groups. Figures are checked against the source before they go live.

Is it free?

Yes. Playing, streaks, badges and leaderboards are free, and your votes stay anonymous.
