I have done an one-way anova test for to compare among 4 groups. I did the homogeneity test for variance and the result showed the variance was not equal but there was a significant difference between group (p=0.013). Thus, I did the Dunnett's T3 test for post-hoc test. However, the p values between all the groups were more than 0.05. How would this happened? Does it mean there are no significant difference between the 4 groups?
Thank you for answering my question.
