I have done a univariate 2 factor ANOVA with spss.

The problem is that the 95% confidence intervall for my mean values (shown in description table) are overlaping each another - and therefore I suppose are not sign. But ANOVA says that the factors have sign effects (testing on interactions was not sign).

I don't know how spss calculates the confidence intervals, but I cannot say the groups have sign means according to ANOVA when my bar chart shows overlapping confidence intervals.

Thanks for help.
