I once used price laddering with the objective to see what percentage of my sample would choose the product at a given price point and how that proportion increased/decreased as I decreased/increased the price. Assuming inverse utility function with increasing price I assume some of your item order is to be rivisited, isn't it? For instance, why would you pose a probably would-would not question in a $45 when the same person already evaluated a $35 and a $55 scenario?

This is a methodology sometimes called "price laddering" and, as Dan, points out, the most likely analysis approach is limited to univariate statistics.

Choice-based conjoint is based on the user making a choice from among a set of alternatives, a few times during such an exercise. The way your questions are structured is not suitable for such an analysis. In general, a conjoint analysis would test more product features than just price. Assuming that the questions below are the only ones asked about the product, I can't really see an opportunity for a more sophisticated analysis beyond descriptive reports.

Dear Lister

I have following questions from a questionnaire, Could you please tell me whether I can conduct Choice-Based Conjoint Analysis using following question sets in SAS/SPSS/Stata? If not, Could you tell me what kind of conjoint analysis we can do for these questions? Your any suggestion will be highly appreciated. Thanks

Hans Zhu
