Hello,
I would like to test the attribute levels for their significance in an HB. I know, there have been a few questions about this. But I am irritated that the primary advice is to do a t-test. If I have more than two attribute levels, then I understand that I should do an ANOVA or MANOVA. Nevertheless, I do not know what the fixed factor in SPSS should be if I only have the utility values of the three levels of an attribute.
Best Regards,
Sebastian
