Randomly Assign Participants to One of Two Scenario Pages in SoSci Survey

Question

Hello,

I am currently creating a survey and need some help with the randomization setup.

My survey contains two different scenarios, which serve as different anchor conditions in an experiment. Each scenario is displayed together with an identical set of questions on a single page. I have already managed to create these two separate pages, so that each page contains one scenario and the corresponding questions.

What I would like to achieve now is a random and approximately equal distribution of participants between these two pages. In other words, each participant should see either Scenario A or Scenario B, but not both, and the assignment should be randomized evenly.

I have tried using the randomizer, but I am struggling to implement the instructions provided in the documentation and tutorials correctly.

Could someone explain how to set up the randomization properly for this use case?

Thank you very much for your help!

Instead of using two different pages, it is often easiert to use a bit PHP code to display varying content on the same page.

Please read this manual to get an idea how randomization works in the online questionnaire: Randomization. Also take a look into the manual Randomization with PHP-Code. If you want to stick to the idea with separate pages, continue reading here: Randomization: Pages

When you're stuck, please feel free to post a follow-up question that goes deeper into details.
