Dear friends,

I have run an ANOVA using a linear variable as dependent and a nominal variable
with five groups as independent (factor). The F test is statistically
significant F(4, 431)=2.54, p=0.036.However, the multiple comparisons have shown
no difference between any two groups (no matter whether I used sheffe, tukeys,
lsd etc). What is the interpretation?

Thanks
Jason
