Preference measurement: Carry out Maximum Difference Scaling online with QuestionPro. That's how easy it is!

Maximum Difference Scaling: Definition and How-to. Use the predefined question types “MaxDiff” in QuestionPro and save yourself time-consuming programming!

What does Maximum Difference Scaling mean?

Maximum Difference Scaling, also known as MaxDiff Scaling, is an extremely efficient method for determining preference differences between a certain number of similar properties or things (preference measurement) and can be viewed as an extension of the simple paired comparison developed by the psychologist and physicist Gustav Theodor Fechner. In Maximum Difference Scaling, which is also often referred to as Best-Worst Scaling, the study participants are shown a specific selection from a total of items to be evaluated, whereby the respondents have to select the element they prefer and the one they least prefer . Ultimately, a meaningful preference model is created from all the answers given by the people surveyed. Maximum Difference Scaling can be carried out quickly and easily using the predefined question types of the Max Diff Analysis in QuestionPro.
