MaxDiff Capabilities

  • Number of items per exercise

    up to 120

    up to 2000

  • Hierarchical Bayes estimation in analysis

  • Item scores report (with confidence intervals and segmentation)

    requires export to app

  • TURF analysis (an optimization search routine for finding optimal sets of items)

    requires export to app

  • Simulations

    requires export to app

  • Prohibitions

  • On-the-fly item ranking results (can be used in follow up questions, skip logic, etc.)

  • Anchored scaling (asking additional questions about whether items are important/not important or buy/no buy; otherwise the item scores are just relative scores )

  • Sparse (showing each item 1 time per respondent instead of the usual 2-3 times)

  • Relevant Items MaxDiff (showing a customized subset of items to each respondent, i.e. most relevant items to the respondent's job function, number of items can differ across respondents)

  • Express (randomly choosing a subset of the total items to show to each respondent across all their MaxDiff sets)

  • Bandit (choosing a subset of the total items to show each respondent across all their MaxDiff sets, where we adaptively oversample items based on previous respondents' preferences)

  • Import/export design file

  • Latent class segmentation
