How to interpret the correlation coefficient

How To Interpret The Correlation Coefficient. A correlation close to 0 indicates no linear relationship between the variables. For example most predictor variables will be at least somewhat related to one another eg. The closer the value of the correlation coefficient is to 1 or 1 the stronger the linear relationship. The larger the absolute value of the coefficient the stronger the relationship between the variables.
