Pearson's r measures the strength and direction of the linear relationship between two variables. It ranges from −1 to +1: values near ±1 indicate strong correlation; near 0 indicate weak or absent correlation.

Calculate the Pearson correlation coefficient (r) and r² between two datasets.
The Pearson correlation coefficient (r) measures the strength and direction of the linear relationship between two continuous variables. It ranges from −1 (perfect negative correlation) to +1 (perfect positive correlation), with 0 indicating no linear correlation. r² indicates the proportion of Y's variance explained by X.
