Correlation Measure
Quantitative Problem Solving in Natural Resources / Relationships Between Variables
"Correlation describes the strength and direction of a linear relationship between two variables. The correlation coefficient r ranges from -1 to 1, with values near +1 indicating strong positive association, values near -1 indicating strong negative association, and values near zero indicating weak or absent linear association. Correlation is useful for identifying relationships in data but does not adequately describe strongly nonlinear dependence."
