Wrong results from ANOVA post hoc
A couple of months ago I have asked JASP team to implement the post hoc analysis for the interaction of groups from a two way ANOVA.
I would like to start thanking the team for the implementation of this test.
Working with my data in JASP I found some weird p values resulted from the post hoc of the interaction of groups.
To compare, I ran the same results in SPSS and GraphPad Prism. The overall ANOVA results are ok, however, as I suspected, the results provided by JASP on post hoc comparisons were wrong (SPSS and Prism presented the same p value between them). I tried all tests available (Tukey, Scheffe, Bonferroni, Holm and Sidak), and all returned wrong values from JASP.
Am I doing something wrong?
Please see attached the tables returned from SPSS and JASP. Also, I am providing a csv file of the data used on these analysis (a created result only for example).
Looking forward for the team reply.
Thanks in advance.
