Correlation Spotter

Can you estimate the correlation coefficient just by looking at a scatter plot? Test your statistical intuition across 10 real-world business scenarios.

How It Works

  • Each round shows a scatter plot of two business variables
  • Use the slider to estimate the Pearson correlation coefficient (r)
  • Values range from −1.0 (perfect negative) to +1.0 (perfect positive)
  • After each guess, see the actual r value and a regression line
  • Closer estimates earn more points — 10 rounds, 100 points possible
