Note: Depending on the mode, total number of items, and items presented per screen, the number of questions used per MaxDiff test will update below the question.

aytm's Advanced MaxDiff has two modes to choose from: Aggregate (formerly Express) and HB (Hierarchical Bayesian). If you would like to use our TURF simulator with a MaxDiff you will need to select the HB option. 

• Aggregate will provide aggregate data using the Logit Regression model
• HB will provide individual utility scores and uses the Hierarchical Bayesian model 

Since ranking a long list of alternatives can be a repetitive task, it's best to let respondents know what to expect. Consider adding an Instruction Text question before the MaxDiff test to let your respondents know what's coming, and/or about how long it will take, especially if the experiment takes 6 or more questions.
