      3. No Correlation:The points on the graph would not represent a line at all. (r = 0 ) Correlation Coefficient (r) - Used to measure how well the data matches a line that would best fit the data.-The correlation coefficient will be a number between -1 and 1. **The closer the number is to 1 or -1, the better the data matches the line of best fit.
