Hi,
I'm running a three-way ANOVA on a multifactorial dataset and it says all three (Device, HRT, Dose) variable has a significant influence on the data. However, when I run multiple comparisons, groupings and significance appear only based on one of the variables (Dose). Why is that and which method should I follow?
Thank you-
