Lesson: Pearson’s Correlation Coefficient Mathematics

Start Practising

In this lesson, we will learn how to calculate and use Pearson’s correlation coefficient, 𝑟, to describe the strength and direction of a linear relationship.

Lesson Plan

Students will be able to

calculate Pearson’s correlation coefficient for bivariate data by hand and using a graphic display calculator,
use the correlation coefficient to describe how two variables correlate with one another,
estimate the correlation coefficient from the scatter diagram of bivariate data.
