I'm hoping somebody can help me out with this question. For a study I did a path analysis, which looks like this:
IV --> Mediatior --> DV IV -->
So I have two IV's leading to my mediator. With SPSS I did two regression analysisses from the IV's to the Mediator.
Now I want to test whether the two regression coefficients are signifficantly different from each other using SPSS, but I have no idea how to do this. Except that I assume that I have to use a T-test, but don't know how.
I have the two regression coefficients, their standard deviation and my N (this n is the same for both regressions, because it's all from one sample).
I suspect that this is pretty basic for some, but my skills in statistics are not that great. So help would be greatly appreciated!
