What is MaxDiff analysis?
MaxDiff, or Maximum Difference scaling, also known as Best-Worst scaling, is defined as a rating/preference scale question where respondents choose the best and the worst option from the given set of options. This question helps surveyors measure preferences to take further action on the product or service.
