I have a few questions also, perhaps you want to think about them before doing any analysis. whatever entity you are measuring using the semantic differential technique, is there any reason to believe the variable is distributed normally in the population. sample data will never be normal, so you want to look to the population or to some theoretical framework. of course, you can use normalized scores, the better question is should you? ity might not matter. regarding (2), the answer, it seems to me, is not the software to use, but rather what are you doing? what is the criterion measure? are there multiple predictors, one of which is binary? is it truly binary or a continuous variable that has been dichotomized? it seems to me you need to step back and ask yourself several conceptual questions about what you are doing and what is the purpose of the investigation. sorry to say that these questions typically need to be answered before you collect data. it looks as if you may have put the cart before the horse!!!
