Amova analysis

Hei,

I run the Amova analysis on three groups, the overall P value was significant among groups, but no significant different for pairwised group. Any help for explanation?

152y-2y-60y Among Within Total
SS 0.540043 0.964886 1.50493
df 2 6 8

Many thanks,

You probably don’t have sufficient power to detect a pairwise difference. It looks like you may only have 2 or 3 samples per group.
