Lesson Plan: Scatter Plots and Lines of Best Fit Mathematics
This lesson plan includes the objectives, prerequisites, and exclusions of the lesson teaching students how to draw lines of best fit for a scatter plot and use them to interpret and make predictions about the data.
Objectives
Students will be able to
- understand how a line of best fit can be used to estimate the relationship between variables,
- draw or identify the most appropriate line of best fit for a scatter plot,
- identify when data is not correlated enough to have a line of best fit,
- identify from a graph whether the values of and in the equation of the line of best fit are positive or negative,
- estimate the value of data at a point, using a drawn line of best fit.
Prerequisites
Students should already be familiar with
- drawing scatter plots,
- linear correlation.
Exclusions
Students will not cover
- nonlinear correlation,
- calculating exact values for the equation of a line of best fit.
