I have run an experiment that uses a 2 (between) x 2 (within) x 2 (within) design. There are 16 observations per participant.
However, one of the within-subjects variables only applies to one of the between-subjects groups.
Thus, I only have 6 means, and not the 8 that would have resulted from a full factorial design.
How do I approach the data analysis?
My initial hunch was to do two 2 (between) x 2 (within) ANOVA for each level of the incomplete within-subject variable.
However, this does not entirely feel right to me.
Is there a more appropriate method?
