The Pearson product-moment correlation coefficient (r) assesses the degree that quantitative variables are linearly related in a sample. Each individual or case must have scores on two quantitative variables (i.e., continuous variables measured on the interval or ratio scales). The significance test for r evaluates whether there is a linear ...

Pearson r. There is a simple and straightforward way to measure correlation between two variables. It is called the Pearson correlation coefficient (r) – named after Karl Pearson who invented it. It's longer name, the Pearson product-moment correlation, is sometimes used. The formula for computing the Pearson r is as follows:
