The Correlation Coefficient, commonly referred to as the R-value, is a statistic used to determine the strength and direction of a linear relationship between two variables. It can take on any value between -1 and +1, where values closer to zero indicate a weaker correlation or no correlation at all, and values close to either extreme of -1 or +1 provide a stronger indication of correlation. In a business context, the Correlation Coefficient enables analysts to draw connections between different sets of data, for example examining how changes in sales affect customer satisfaction ratings.
