    Solution

    The correlation coefficient, which measures the strength and direction of a linear relationship between two variables, ranges from -1 to +1. -1 indicates a perfect negative linear correlation, +1 indicates a perfect positive linear correlation, and 0 indicates no linear correlation. Values outside this range, such as -2 or +2, are not possible.
