Hello,

We are currently hosting an experiment using a combination of Qualtrics and Inquisit and are stumped about a random assignment issue. We have 6 between subjects conditions. Right now, participants complete the consent form in Qualtrics, which then randomly (and evenly) sends them to the task with one of six links that have a URL query parameter that defines the condition. Inquisit then uses this parameter as the group number and loads the correct task. 

The problem we're having is that some of the participants (MTurkers) quit the study after Qualtrics sends them to the task. In this case, Qualtrics does not know that the experiment wasn't completed and continues to randomly assign to the conditions as though the cell counts are even. Some of our cell counts are therefore less than others, as by chance, participants have quit more within certain conditions than in others. 

We would like to re-run this study and are wondering if there a way to use random assignment methods in Inquisit that would update the condition counts only if the task was completed? Or any other way that would get around this issue?
