Exercise:
Four different stimulations (A1, A2, A3, and A4) were applied to 8 subjects, and the subjects’ responses were compared between pre- and post-stimulation. Changes in response were quantified by subtracting pre-stimulation response from post-stimulation response in each subject.
Analyze whether magnitudes of response are different depending on types of stimulation.
Comparative Verification Test
Friedman test: StatFinale, 0.000616; SPSS, 0.001; EZR, 0.000616.
Multiple comparisons
Multiple C (Nemenyi & Conover tests): StatFinale Conover’s test needs the Bonferroni correction.
Multiple C (Dunn test with Bonferroni correction): SPSS
Multiple C (Wilcoxon test with Bonferroni & Holm correction): EZR (match with StatMate-pairWC).
Reports of SPSS & EZR
In the Wilcoxon test of EZR, data with a difference of 0 is automatically removed, and the Bonferroni & Holm corrections are applied to the normal approximation as post hoc tests.
