Hi group,
I have to design the paired ttest for multiple subgroups for 80 patients
with tumor and their respective normal samples. I am new to using multiple
groups and I have normally used just tumor versus control.
Subgroups:
 Group(160)-   Tumor(80),     Normal(80)
Gender(80)-   Female(27),    Male(53)
Stage(80)-     I(4),      II(7),        III(54),        IV(15)
Waiting for your suggestion on design,
Thanks,
Viritha
