the exam results.
Here is some sample data:
------------

whichExam=factor(c(1,2,1,2,1,2,1,2,1,2,1,2,1,2,1,2)),
studyMethod=factor(c(1,0,1,0,1,0,1,0,0,1,0,1,0,1,0,1)),

------------
From what I have read this should be how to compute and ANOVA on this data:
------------
> summary(aov(score~whichExam*studyMethod+Error(particID),data=dataSet))
Error: par...
