Hi guys,

I am writing my thesis at the moment but I'm kinda stuck. I have two main questions:

- My independent variable is nominal (dummy 0-1), dependent variable is interval (scale 1-7), my moderator is nominal (dummy 0-1). What test do I use using SPSS? For now on I use a linear regression, however I have read that for a linear regression both independent and dependent variable need to be interval variables, which is not the case.

- For my correlation analysis, do I need to include the moderating effect? Meaning 'moderator x independent variable'? Or do I just include 'moderator'. I am wondering since if I only include 'moderator', I measure the correlation between the moderator and the dependent variable, rather than the moderating effect (moderator x independent variable) on the dependent variable.

I would highly appreciate if anyone can answer my questions, so I can finish my thesis.
