group assignment web inquisit

Hello, we are trying to launch an online experiment, where the participant will complete an online task every day in the same pre-determined condition. How to set up the experiment in the way that partcipants do select the right condition (how to define participants IDs and group Ids).

<batch GroupA>
/subjects = (1 of 2)
/ file= "OnlineCondition1.iqx"
</batch>

<batch GroupB>
/subjects = (2 of 2)
/ file= "OnlineCondition2.iqx"
</batch>

Thank you!

Set your <batch> elements up to assign based on group id:

<batch GroupA>
/subjects = (1 of 2)
/ groupassignment = groupnumber
/ file= "OnlineCondition1.iqx"
</batch>

<batch GroupB>
/subjects = (2 of 2)
/ groupassignment = groupnumber
/ file= "OnlineCondition2.iqx"
</batch>

In your web experiment's settings, select the "URL parameter" option under "How Group IDs should be generated."

Then, give out to different links. To participants who should complete the 1st condition:

To participants who should complete the 2nd condition:

https://research.millisecond.com/yourexperminent.web?groupnumber=2
