MaxDiff is a statistical method. Survey Analytics's Advance MaxDiff Software, survey respondents can be shown a set of the possible items and are asked to indicate the best and worst items (or most and least important, or most and least appealing , etc.).

MaxDiff may be thought of as a variation of the method of Paired Comparisons.
