Geogebra: Residuals and Linear Regression

Curated and Reviewed by Lesson Planet
This Geogebra: Residuals and Linear Regression interactive also includes:

If the line fits, use it. Using a Geogebra interactive, pupils plot points and try to find the best fit line. They assess the linear fit by analyzing residuals. A radio button allows participants to show the regression line and the plotted residuals.

Instructional Ideas
  • Provide a short lesson on using residuals to assess the fit of a linear function
  • Lead a discussion on ways to find a best-fit line other than eye balling it
Classroom Considerations
  • The class should understand how to eye-ball a best-fit line
Pros
  • Lets users move the line incrementally
  • The user can enter their own points or let the resource randomly generate them
Cons
  • None
