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
