Complete Answer
The correlation coefficient, denoted as \(r\), is a numerical measure that quantifies the strength and direction of a linear relationship between two variables. It ranges from -1 to +1, where values close to -1 or +1 indicate a strong linear correlation, and values close to 0 indicate a weak linear correlation. A strong correlation between two variables does not imply causation because correlation only measures association, not a cause-and-effect relationship. Other factors, such as confounding variables or coincidence, might be responsible for the observed relationship.
