Hi guys,
I have a question regarding group statistics with unbalanced number of subjects in each group.
I need to run an ANOVA with factor GROUP (HV, PatientGroup1, PatientGroup2, PatientGroup3) and TASK (Speech, syllable1, syllable2).
The problem is that I cannot run 3dANOVA3 because of unbalanced number of subjects in each group (27 HV, 27 PatientGroup1, 26 PatientGroup2, 20 PatientGroup3). The third group of patients is really rare and it would be a shame to remove 7 patients from the other groups.
Can someone help me in solving this problem?
thanks
