Hi community!
Currently finalising my Master thesis research. I manipulated my independent variable to have three conditions. Originally, I proposed a 3(3 conditions of independent v)x2 (dichotomous moderator)factorial design. However, the moderator records the environmental consciousness of participants and is actually continuous. I can split it up into high and low to turn it into the proposed factorial design but I do not know if I should.
I ran the analysis with the continuous moderator in SPSS with PROCESS and got significant (p
The PROCEESS program is based on standard deviation values, mean-1SD/mean/mean+1SD
It all depends on the justification of how you categorize your moderator variable.
Google moderation research Virginia R and you will get some materials that should be very helpful. Best, David Booth
Ps categorizing usually discards information. I would avoid if possible
I agree that splitting the continuous variable into two categories will result in the loss of information, perhaps to the extent of missing a significant effect that would have been detected by the continuous version.
That said, interpreting moderation with continuous variables requires more effort than when you have just two categories, so be sure to focus your search on moderation with continuous variables.
Thank you David L Morgan !
I keep reading that it is more difficult to interpret continuous moderators but I can't find why that is. How can I interpret it in a robust way?
