Hi all,

I would really appreciate it if you could help me with the following: I am doing my thesis research about the effect of company misconduct on purchase behaviour. The misconduct is the moderator variable and I am also testing for mediation of brand attitude. To test the effect, I have conducted an experiment. I used two different fictitious companies (for generalisation ) and industries  in my questionnaire so essentially I have 4 conditions: 

1. Company A and Company B- industry A- no misconduct (control group)
2. Company A and Company B- industry B- no misconduct (control group)
3. Company A and Company B- industry A- misconduct
4. Company A and Company B- industry B- misconduct

Now that I have all the data, my supervisor advised me to do a pooled regression. I have seen that other similar studies used the univariate analysis, so I am still not sure if a pooled regression is the right method. However I still would like to know how I can run the pooled regression in SPSS.

Thank you in advance.
