I've some troubles making a analysis in SPSS and I hope that you can help me out.
Independent variable: Formality (ranges from 0-15)
Dependent variable: Performance (ranges from 0-25)
Moderator: Firm Size (small or medium-sized)
My teacher told me to use a linear regression model.
So, I did the following.
Created moderator effect by multiplying firm size with formality.
Analyze > Regression > Linear
Filled in: Dependent variable : Performance
Independent variable: Formality and Firm size (box 1) and Moderator effect (box 2)
And then: OK
Is this the right analysis?
Thanks in advance
