Is it possible to group and randomise a set of questions?

Also: Can I randomise the order of question groups i.e. randomisation blocks?


Yes, our platform allows you to both group sets of questions and also randomise which/how many questions your respondents are shown through the “Randomisation block” feature.

To set up the “Randomisation block” feature:

  • Open your experiment and select the “Additional settings” tab.
  • Click the “Add question” button and select the “Randomisation block” option and enter your preferred maximum number of questions to display per respondent in the form below. Enter 0 to display all questions in the block to all respondents.
  • Add each question you want in the block and hover over each in the left-hand menu to make the move tool icon appear.
  • Click the move tool icon and drag each question under the “Randomisation block” element to group them together.
  • Click the “Save changes” button at the bottom of your screen.

As each question in the block is entirely randomised, it is not guaranteed that each will be shown to an equal number of participants. However, questions are allocated to an approximate equal number of participants, e.g. for a randomisation block with 2 questions, each question will be shown to approximately 50% of participants.

Can I randomise the order of question groups i.e. randomisation blocks?

Yes, randomising question groups on Conjoint.ly is easy using nested randomisation blocks. You can nest two or more randomisation blocks inside another block, as shown below.
