Guess the Correlation is a straightforward game where you do just that, and it’s surprisingly fun. You get a scatterplot and you guess the correlation coefficient. That’s it. If you’re off by too much, you lose a life, and if you’re almost spot on, you gain a life. If you’re somewhat right, you get a coin. Bonus points for streaks of correct guesses.
