Hi everyone,
I got a manipulation check (with 3 measurement items) and it is mainly to determine that the groups i am comparing are indeed significantly different (i.e. high level vs low level).
I have been searching for related articles but mostly are experimental studies. I have no idea which test should i apply. Can anyone help me with this? Thanks in advance!!
Best regards,
Catherine

Hi,
1) Comparison of means:
ANOVA for three or more groups
t-test for 2 groups.
Or their nonparametric versions (Kruskal-Wallis and Man-Whitney).
2) For model comparison (path coefficients): Use the search function in this forum and look for “multigroup comparison” or “multigroup analysis”.
