The correlation coefficient is a statistical measure that calculates the strength and direction of the relationship between two variables. It ranges from -1 to 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation at all. This measure is essential in understanding data patterns and trends, especially when using functions to model real-world phenomena.
