Nested ANOVA in SPSS
http://www2.chass.ncsu.edu/garson/PA765/anova.htm
Modify SPSS syntax:
/DESIGN = mainfactor nestedfactor(mainfactor)
which is used to signify that the model is the main effect of the fixed factor plus the effects of the random nested factor at each value of the main fixed factor. In the syntax window, Run All. In the resulting ANOVA table, a significant nestedfactor(mainfactor) effect means that the dependent variable varies by the nested factor even within the same level of (controlling for) the main factor.
