Different results with paired t-test and ANOVA post-hoc paired t-test
I recently tried to reproduce some analyses my professor conducted in SPSS. I could reproduce the ANOVA, however the post-hoc paired t-tests gave minimally different results. I then reproduced the post-hoc t-tests in R, which gives identical results to SPSS. After further experimentation I noticed that also the t-test function in JASP gives the same results as SPSS/R.
Therefore, I´d like to know how the calculation of the paired t-tests in JASP is different when using the t-test function compared to doing ANOVA post-hoc t-tests.
The differences are quite small, but noticable, for example t = 27.28 vs t = 27.35.
