Hi,
my post is somehow inspired by that post:
https://forum.posit.co/t/post-hoc-after-chi-square-test/149329
But what would be an interpretation of the results ? Which group is compared with which ?
Additionally I have tried to recreate these post-hoc test for chi square from here (at the bottom of that page there is an edu-marit.sav file for download):
https://www.spss-tutorials.com/spss-chi-square-test-with-pairwise-z-tests/#google_vignette
So I have done a following crosstable and then a relevant matrix in R:
library(chisq.posthoc.test)
chisq_matrix <- as.table(rbind(c(18, 36, 21, 9, 6),
c(12, 36, 45, 36, 21),
c(6, 9, 9, 3, 3),
c(3, 9, 9, 6, 3)))
dimnames(chisq_matrix) <- list(Marital_status = c("Never_married", "Married", "Divorced", "Widowed"),
Education_level = c("Middleschoolorlower", "Highschool", "Bachelors", "Masters", "PhDorhigher"))
getting this result:
or:
library(RVAideMemoire)
chisq.theo.multcomp(chisq_matrix, p.method = "bonferroni")
getting that:
I would like to ask for help with interpretation which group was compared with which and to compare results with Z-test performed in SPSS that saying:
in Never married level Middle school or lower group (significantly) differs from Master's group, which is NOT clearly visible looking at results I have obtained from R. Any help would be much appreciated, thank you.
