Post hoc t-tests: different results using different software
I performed a Repeated measures ANOVA (2x2) with JASP and SPSS. The results of a post hoc t-test are very different. Using SPSS, the p-value of a post hoc t-test is 0.001 while using Jasp, this post hoc t-test is not significant (p=0.719).
Has anyone had the same problem and can explain to me why there is such a big difference in results between the different software?
