BlockSurvey allows you to easily randomize question groups and limit the number of groups shown to each respondent. This guide will walk you through the steps to achieve this:
Prepare the questions you want to randomize are organized into distinct groups. The groups should be placed sequentially in the survey flow.
For example: Group A, Group B, Group C, Group D.
Go to Settings -> Question Randomization.
Toggle on Enable question shuffle / randomize. In the Start dropdown, select Group A, and in the End dropdown, select Group D. This will randomize the questions within the range.
Toggle on Maximum number of questions per respondent and set the value to limit the number of question groups shown to respondents.
For example: To show only 2 out of 4 groups: Set the value to 2 to restrict the display to only two question groups.
That's it! You're all set to randomize question groups using BlockSurvey.
