Building an Advanced MaxDiff
MaxDiff tests are helpful when comparing a long list of alternatives. You can add between seven and 200 alternatives for respondents to compare in sets of three, four, or five alternatives per screen.
Building a MaxDiff
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. |

Selecting methodology
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. |

Best Practices in MaxDiff
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. |
