Between group variation measures how much the group means vary from the overall mean (SS between). Steps in SPSS Residuals should be normally distributed Use the Save menu within GLM to request the standardised residuals for each subject to be added to the dataset and then use Analyze Descriptive Statistics Explore to produce histograms/ QQ plot / Shapiro Wilk tests of residuals. If the residuals are very skewed, the results of the ANOVA are less Head back to Page 2.7 of our previous module if you need to jog your memory about how to do all of this on SPSS. We should also obtain some useful new variables from the Save menu.

This is done with the SAVE FILE command. Example: SAVE OUTFILE = 'd:\mydirectory\mysubdirectory\mydata.sav'. where you have to fill in your directory and data set This formula allows us to COMPUTE our predicted values in SPSS -and the exent to which they differ from the actual values, the residuals. However, an easier way to obtain these is rerunning our chosen regression model. Inspecting them tells us to what extent our regression assumptions are met.

So, if a dataset has 100 total observations then the model will produce 100 predicted values, which results in 100 total residuals. The sum of all residuals adds up to zero. The mean value of the residuals is zero. Step 5: Create a predicted values vs.
