Post Hoc Analysis

[Veronica123]

Hi,

I am having trouble running a post-hoc analysis as I keep recieving the message: "Post hoc tests are not performed for EmpathyMean/AltruismMean because at least one group has fewer than two cases."

I am trying to compare the means between two independent variables (Altruism & Empathy) and how they may work together to determine the dependent variable (Charitable Donations).

Please could someone advise me on what I can do to perform this analysis.

Well are there two observations for that group or is that message incorrect?
