You have been asked to develop a scale that assesses the relative importance of factors that influence the purchase of a smartphone. Begin by listing the product attributes or other factors that you believe could be influential. If the choice was between a ranking scale, a paired comparison scale, and a constant sum scale, which would you use and why? If the choice was between an itemized rating scale, a Likert scale, and a semantic differential scale, which would you use and why? Develop the scale type you ultimately would select given all possibilities, and defend your recommendation.
