A residual is the difference between an observed value of the response variable and the value predicted by the regression line. residual = observed value of y – predicted value of y. A residual plot is a graph of the regression residuals plotted against the explanatory variable x. Residual plots help us assess the fit of a regression line.

The normality assumption means that the residual errors are assumed to be normally distributed, roughly in the shape of the normal curve. We check this assumption by examining histograms of each group. At the Graphs menu, select Legacy Dialogs.

Bring into SPSS the Residual-HETERO.dat data. Each case has two scores, X and Y. The delimiter is a blank space. Conduct a regression analysis predicting Y from X. Create residuals plots and save the standardized residuals as we have been doing with each analysis. As you can see, the residuals plot shows clear evidence of heteroscedasticity.

Line plot of the residual. Durbin - Watson Appendix I: Testing for Normality By Using a Q-Q Plot. A natural question in applying a normal distribution is: how can we test whether the the data actually come from a normal distribution? A simple method is to construct a histogram, and compare the shape with the normal distribution that has the ...
