#-1# to #1#

Explanation:

Correlation coefficient is the measure of linear strength between two variables, and it can only take value form #-1# to #1#

Negative values implying a negative (downward) relationship, while positive values imply a positive (downhill) relationship.

The strength of relationship is given by magnitude of correlation, so correlation of #-1# and #1# represent perfect linear relationship.
