Max-diff is a recent development in statistical analysis. It is a comparative method in which respondents are shown sets of items and asked to pick the best and worst, or most and least important item, in each set…. Since respondents have to make comparisons and choices, the problems mentioned with traditional importance scales are largely absent
Philadelphia, PA (PRWEB) November 25, 2009
In his article published in the November issue of Quirk's Marketing Research Review, titled "How to Improve your Segmentations with Max-Diff", Rajan Sambandam, Chief Research Officer at TRC Market Research explains how maximum difference scaling, or max-diff, can deliver finely-tuned segmentations without subjecting respondents to an onerous number of comparison questions. "Max-diff is a recent development in statistical analysis. It is a comparative method in which respondents are shown sets of items and asked to pick the best and worst, or most and least important item, in each set…. Since respondents have to make comparisons and choices, the problems mentioned with traditional importance scales are largely absent," Rajan Sambandam explains.
A split sample was used to demonstrate the benefits of max-diff technique. One-half of the sample was asked to rate features important to respondents in opening a checking account, using a 10-point importance scale. The other half was given a max-diff task. As the article explains, the analysis from the max-diff half of the sample yielded more clearly differentiated segments, providing study results that would be more valuable to a client.
