Multiple Regression - Interaction- SPSS (part 1)

I demonstrate how to test an interaction (moderator) hypothesis via multiple regression. I use a centering methodology to reduce multicolinearity. Additionally, I demonstrate an easy to perform method to depict the effect of an interaction effect with a scatter plot.

Help in data manipulation
First of all I want to say thank you for your videos they have helped a lot during my projects.
Have a request: can you do a video on moderated mediation analysis
I do have a question about data manipulation.:
I have 4 conditions and a control group. When I am creating my scale (e.g. brand equity) and checking for credibility and so on. Do I include the control group's data or should these be in a separate SPSS file or splitfile.

thanks so much....you have been my best stats guru!!

I'm just curious but wouldn't a potential criticism of this technique of centring be that you end up effectively combining data points? In explanation the "hassles with support" and the "no hassles with no support" data points are treated as the same once centred and multiplied. My guess is that this is what happens in other tests of interactions anyway, for example in a factorial 2X2 ANOVA, is this correct?

Great videos, thanks for your help!

(1) Great videos! (2) How do we interpret the economic meaning of the coefficient for an interaction variable?
