The coefficient of correlation r measures the strength and direction of a linear relationship between two variables. Values of r range from -1 to 1, where 1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and values closer to 0 indicate a weaker linear relationship. The strength of the correlation is determined by the absolute value of r, regardless of the sign. Therefore, -0.75 indicates a stronger correlation than 0.65 because its absolute value (0.75) is greater than 0.65.
