Welcome to the Lab โ€“ where you feel the data.

In this playful little statistics lab, your task is simple โ€“ and surprisingly satisfying:
Drag the Dotkins straight up or down to adjust their y-positions until the Pearson correlation coefficient (r) matches the given target.

๐ŸŽฏ The x-values are fixed โ€“ only the vertical position of each Dotkin can be changed.

With each round, youโ€™ll intuitively explore:

  • ๐Ÿ”ป What strong negative correlations look like

  • ๐Ÿ”บ How strong positive correlations are structured

  • โž– What it means when r is close to zero

  • ๐Ÿค“ And how subtle shifts affect the strength of a relationship

As you level up, the target correlations become more precise โ€“
requiring you to match r-values to the third decimal place.

๐Ÿงช How to play:

๐Ÿ‘‰ Click and drag a Dotkin straight up or down
๐Ÿ‘‰ Watch how the "current r" changes in real time
๐Ÿ‘‰ Release the Dotkin when you're satisfied with the pattern
๐ŸŽฏ Match the target and move on to the next challenge!

  • ๐Ÿง  Designed to build an intuitive sense for correlation โ€“ no formulas needed

  • ๐ŸŽฎ Built in Unity

  • ๐Ÿ™‚ Featuring colorful Dotkins who love a good data makeover
