SPSS ANOVA w/Tukey's B interpretation...

#1
Hi!

I'm having a bit of trouble interpretting some results. I did an ANOVA w/post-hoc. The p-value for the ANOVA was 0.022, however, the post-hoc shows no statistically significant differences between groups (all groups are in the same column in the homogeneous subset box).

How is this possible?

Thanks!

Did you try other post-hoc tests that are not as conservative as Tukey's e.g. Student Neuman and Keuls (S-N-K) or Ryan's (REGWQ) tests?
