correlation coefficient
Quantifies linear relationship strength
A correlation coefficient is a number that measures how closely two variables move together.
Values range from −1 (perfect inverse relationship) to +1 (perfect direct relationship), with 0 indicating no linear relationship.
The most common type is the Pearson correlation coefficient: The correlation coefficient between height and weight was 0.7.
