Product Moment Correlation (Pearson's r) Explanation: Pearson's Product-Moment Correlation Coefficient (r) measures the strength and direction of a linear* relationship between two quantitative variables. Its value ranges from -1 to +1, where +1 indicates a perfect positive linear relationship, -1 indicates a perfect negative linear relationship, and 0 indicates no linear relationship. Formula: r = n( xy) - ( x)( y)[n( x^2) - ( x)^2][n( y^2) - (\
