| Source | Wolfram Demonstrations Project |
| Description | For one several data sets for which number of points and errors can be adjusted, users try to find least squares line guided by squared errors and total error (shown graphically) before showing actual regression line, also has option for quadratic functions. Requires download of Mathematica Player as well as demo itself, good for classroom demonstration. |
