Intro to Probability
The correlation coefficient is a statistical measure that describes the strength and direction of a relationship between two variables. It provides a value between -1 and 1, where -1 indicates a perfect negative correlation, 1 indicates a perfect positive correlation, and 0 indicates no correlation. Understanding the correlation coefficient is vital as it relates to the covariance of random variables, helps in analyzing joint distributions, reveals properties of relationships between variables, and has various applications in fields such as finance and social sciences.
