Hey, just wondering if anyone can provide some assistance on this stats question. I am working on doing a moderation analysis and have been searching the internet and books for some instrcutions on how to do this (if you have any recommendation for resources, that would also be wonderful...).
Here is what I have come up with so far from my readings and I an wondering if I am doing it right:
Step 1 - Some sources say I would need to center the variable first, others say it is not necessary. Anyone have any advice on this?
Step 2 - Multiply the variables by the moderator.
Step 3 - Multiple regression with the predictor variable, the moderator, and their product entered. Is this all entered at once or is this a step-wise regression?
If the product of the variables is significant, then there is moderation? Does it matter if the initial variable and the moderator are individually significant or not?
