To establish the strength of a linear association, first compute the correlation coefficient between the variables involved.

The, examine the absolute value of the coefficient.

A strong relationship has an absolute value of close to 1 (or approaching 1) while a weak relationship has an absolute value close to 0 (or approaching zero).
