Pearson Correlation Coefficient Calculator

Pearson’s correlation coefficient is a measure of the linear correlation between two variables X and Y.

Denoted as r, Pearson’s correlation coefficient has a value between -1 and 1, where 1 indicates a perfect positive linear correlation between variables X and Y, 0 indicates no linear correlation, and −1 indicates perfect negative linear correlation.
