Randomized groups w embedded data - 1 out of 4 times Block is not displayed | XM Community
Skip to main content

Hello everyone,

I am writing my master thesis and the survey is the basis for all the test. I hope you can help me.

 

Explanation

I have created a survey with 5 randomized groups:

  1. Germany_NC
  2. Germany_EA
  3. Spain_ NC
  4. Spain_ EA
  5. CG

The logic goes like this:

  1. If the participant is German and it gets randomly the “Germany_ NC” group, then the participant gets assigned the Question Block “Information provision_Nature Connection_Germany”.

The same goes for the others:

  1. German Participant + “Germany_EA” group = “Information provision _Eco-Anxiety_Germany” Block.
  2. Spanish Participant + “Spain_ NC” group = “Information provision_Nature Connection_Spain” Block.
  3. Spanish Participant + “Spain_ EA” group = “Information provision _Eco-Anxiety_Spain” Block.
  4. “CG” group = “Information Provision_Control Group” Block. (In this one it does not matter which nationality the participant is, since the content of the block is the same for both nationalities.)

I have made trials to check if it works. I have made the survey 3 times as a Spanish and each of the time I got assigned to one of the correct groups: Spain_NC, Spain_EA or Control Group. However, the 4th time, instead of showing up again one of the previous blocks, it just skips it and does not show any randomized group. So to be more clear: the 4th time the “Demographic Questions” Block is displayed and right after the “Pro-environmental behavior” is displayed.

Please see schreenshots of the Survey flow:

 

 

Question

Does anyone know why the randomized group is skipped?

Does anyone know how to solve this issue? Or had a similar issue?

 

Thank you!

@EvaGA Your nationality question and the group randomizer are completely unsynchronize. You can be Spanish and got assigned to German treatment and satisfy none of those 5 branches (You just got lucky the first 3 times, be a Spanish and got assigned to a Spanish group)
Solution is make 2 branches with 2 randomizer, 1 for German and 1 for Spanish.


 Hey @Nam Nguyen thank you very much for your response! 

I have changed the Survey Flow based on what you said:

 

I hope I understood you properly, is this what you meant? Is it correct now?

Thanks😀!


@EvaGA Yes, in that way German will get the only 3 possible German outcomes, the same with Spanish. Test it yourself and see the difference 👍
