Dear SPMers,
We're currently studying the maturation of brain and already obtained a
dataset containing 3 age groups. We want to test the effect of age,
gender and interaction between them. So we try to use two way anova to
analyze our data. I've read Drs. R. Henson and W. Penny's excellent
technical report"Anovas and SPM", I wonder whether it is appropriate to
apply the same technique by coding (1st age group female) as (group 1),
(2nd age group female) as (group 2),..., (3rd age group male) as (group
6) since our data is not balanced and in the report the data seems to be
all balanced.
Thanks in advance!
