A residual plot graphs the residuals of a line of a best fit on the vertical axis and the independent variable on the horizontal axis. Residual plots can be used to determine whether a linear model is appropriate for the data.This video shows how to create and interpret residual plots using CODAP (Common Online Data Analysis Platform) which can be accessed for free at codap.concord.org.
