MaxDiff is a type of survey questioning approach in which respondents are presented with lists of items and are asked to indicate which in each list they like the most and which they like the least. It is also known as best-worst scaling, max diff, max-diff, maximum difference scaling, and Max Differential Scale Data. An example of a MaxDiff question is shown below. Typically respondents are asked to complete multiple similar tasks, where the options shown in each task varies according to an experimental design.
