13 maj 2022 · The Pearson correlation coefficient (r) is the most common way of measuring a linear correlation. It is a number between –1 and 1 that measures the strength and direction of the relationship between two variables. When one variable changes, the other variable changes in the same direction.
This Pearson correlation calculator helps you determine Pearson's r for any given two variable dataset. Below, we explain what Pearson correlation is, give you the mathematical formula, and teach how to calculate the Pearson correlation by hand.
