I put up a study a week back but due to an error (not on the side of Prolific but of the other platform I used to run the survey) I now have uneven distributed people in 8 groups (I split the survey so that questions were slightly different in 8 groups). I aimed to have 144 people per group. I now have have around 120 people in 7 groups and 250 people in one group.
Is it possible to re-open the study in order to get to the desired 144 people per group? Of course I will delete one group, the one for which I have more than I need participants for.
Would it be possible to get new people doing the study? I want to make sure that they are different people.
Also, would this affect the representativeness of the groups? I initally had ticked that I want a representative sample and with support from Prolific I was also able to have other inclusion criteria added.
Thank you in advance!
