I performed Fisher's exact test on a 4*2 table in SPSS, and I got a significant difference (P= 0.010) and I wonder what is the post hoc test to use following that?

Is it the adjusted standardized residuals? and if I want to calculate the P value from each adjusted standardized residuals, how can I do that?

  • $\begingroup$ You can test all six 2*2 tables with the same procedure and then apply a generic multiplicity correction like Holm's. There might exist more powerful approaches though. $\endgroup$

  • $\begingroup$ Fisher's exact test is not very accurate so why use it? $\endgroup$ Sep 3, 2023 at 19:35
  • $\begingroup$ Hi Michael M. Could you please explain how to convert the 4*2 table to six 2*2 tables? $\endgroup$ Sep 5, 2023 at 7:58
  • $\begingroup$ Hi Frank Harrell. I used Fisher's exact test because the assumptions of Chi Square test were violated. $\endgroup$ Sep 5, 2023 at 7:59
