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
