Compute the linear correlation coefficient. The linear correlation coefficient for the four pieces of data is _______.
(Round to three decimal places as needed).

Definition Definition Statistical measure used to assess the strength and direction of relationships between two variables. Correlation coefficients range between -1 and 1. A coefficient value of 0 indicates that there is no relationship between the variables, whereas a -1 or 1 indicates that there is a perfect negative or positive correlation.
