Residual Plots, Years 11–12
Students discover what a residual is, calculate residuals for a fitted line, and learn to read the resulting residual plot to judge whether a linear model suits the data. The full interactive is available to licensed Education Universe users.
Years 11–12Explorer
Learning outcomes
- Calculate residuals.
- Construct and read a residual plot.
- Judge whether a linear model is appropriate.
Teaching guidance
Show a data set with a curved pattern and ask whether the line is a good model before showing the residual plot.
