๐Ÿ“ˆ Pearson Correlation: Linear Power

Use Pearson when your data has a linear trend โ€” one variable rises (or falls) proportionally with another.

Perfect for normally distributed, continuous data.

๐Ÿ’ก Examples:

Advertising spend vs. sales revenue

Height vs. weight

Temperature vs. energy use

When was the last time you saw a perfectly linear trend in your data?
