The following table compares the completion percentage and interception percentage of 5 NFL quarterbacks.

Completion Percentage	55	56	57.5	59.5	60
Interception Percentage	4.5	44	2.5	2	1.5

Copy Data

Calculate the correlation coefficient, r. Round your answer to three decimal places.

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.
