To determine what it means for ∑ i = 1 n ( x i − x ‾ ) ( y i − y ‾ ) to be "large," we standardize this sum first by dividing by n − 1 and then by dividing . The larger the number, the stronger the relationship. The correlation coefficient is a measure of how well a line can describe the relationship between x and y.

The absolute value of the correlation coefficient gives us the relationship strength.
