Finding Residual Standard Deviation & Coefficient of Determination – Statistics Tutorials

This video looks at two of the trickiest parts of a regression analysis: Residual Standard Deviation and r^2, the Coefficient of Determination. We'll see how to find each summary in Google Sheets, but more importantly we'll also talk about what these numerical summaries can tell us about a data set, and how they are used in real life. I made this video to help my Statistics classes with their quarter 3 project about correlation, scatterplots, and regression analysis.
