Calculate Pearson's Correlation Coefficient (r) and R-Squared for two distinct datasets.
Reference Module v1.0
Do two things move together? The Correlation Calculator computes Pearson's r, measuring the strength and direction of the linear relationship between two variables.
Scatter plots can be deceiving. This tool gives you a precise number between -1 and 1. +1 is perfect positive correlation, -1 is perfect negative, and 0 is no relationship.

Correlation does not imply causation! Just because ice cream sales and shark attacks both go up in summer (correlation) doesn't mean ice cream causes shark attacks.
