correlation coefficient

A correlation coefficient is a statistical measure that quantifies the strength and direction of the relationship between two variables. It provides a single numerical value that ranges between -1 and +1, where a positive value indicates a positive relationship and a negative value represents a negative relationship. The closer the correlation coefficient is to -1 or +1, the stronger the relationship, while a value close to 0 suggests a weak or no relationship between the variables.
