Have anyone encounter that two-way repeated measures anova gives wrong mean values?
I am using two-way repeated measures anova to analyze my data. In some sets of data, the two-way repeated measures anova always gives mean values different from the mean values that I calculated in excel. I tried using t-test or one-way anova to test the same data, these two always give me the same mean values with excel. I tried multiple times, the results are the same. The data is normally distributed. The version is OriginPro 8. Can anyone help to explain why this happens? Thank you!
