Abstract
We offer an interactive spreadsheet to teach simple linear regression, which we have found to be an effective teaching tool. Unlike most textbooks that cover regression, this spreadsheet displays what is being minimized—the squares of the errors—and it allows students to experiment with the parameters of the line before optimizing them.
