Is there a way to change the "evenly displayed" in Qualtrics to some probability-based randomization (either in survey flow or question randomization)?

  • Hi, Qualtrics has a randomizer Block that you can use. Is this what you are after? [link](http://www.qualtrics.com/university/researchsuite/advanced-building/survey-flow/block-randomization/) – AngularJR May 15 '15 at 01:31
  • Not really. I need to randomize with some probability, say some questions are more likely to be displayed than others (but I can't use "edit count" because the probability is conditional on subject's choice in previous questions). I'm thinking of some javascript codes, but really don't have a clue.. – Tracy Lee May 15 '15 at 19:19
  • Take a look at this, it looks like you can use Javascript to set/choose Q/A. [Click Here](http://www.qualtrics.com/university/researchsuite/developer-tools/custom-programming/survey-javascript-methods#AnswerChoices) – AngularJR May 15 '15 at 21:23
  • The only way I can think to do this is to setup a web service that determines the block to show and sets a piece of embedded data based on which block to show. – Anthony Rivas May 19 '15 at 15:36
  • Did you manage to solve this problem eventually? 2 years later and this problem still exists. – Peter Jul 14 '17 at 09:37
  • I'm using an adaptation of [this](https://stackoverflow.com/questions/3983660/probability-in-javascript-help/3983830#3983830) javascript answer to a similar problem. You can plug the output into embedded data, then use the embedded data to inform which blocks or questions are shown. – Molly OW Oct 16 '17 at 18:54
