Numerical Measure of Linear Association Between Two Variables

Measures of association are used in various fields of research but are especially common in the areas of epidemiology and psychology where they frequently are used to quantify relationships between exposures and diseases or behaviours. The Pearson product-moment correlation coefficient measures the strength of the linear association between variables.

Linear Relationship Definition

Positive relation between two variables.
