# Lesson Plan: Correlation Mathematics • 8th Grade

This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to deal with linear correlation and distinguish between different types of correlation.

#### Objectives

Students will be able to

• understand and describe how two different variables can be related,
• determine if two different variables have a linear or nonlinear relationship,
• describe the relationship between two different variables in terms of positive and negative correlation,
• describe how strongly correlated two different variables are based on the proximity to a line of best fit on a scattergraph or a scattergraph without a line of best fit.

#### Prerequisites

Students should already be familiar with

• plotting coordinates on scattergraphs to show the relation between two variables,
• line of best fit,
• one-variable statistics.

#### Exclusions

Students will not cover

• calculating the correlation coefficient for two variables,
• finding the equation of the line of best fit.
