Hello,
I am looking at students confidence in a subject by giving the same survey three different times throughout the year. I want responses to be anonymous (as per ethics approval) but need a way to connect the responses to compare an individuals response at survey 1, 2 then 3.
I have created the survey and will have the students name/email addresses who consent to be involved. So I was thinking of having them create a unique number (some memorable combination of house number/month of birth/end of student ID) which can be used to ID their response.
I’ve looked into query strings but cant make any sense of it and the community page but I have never used Qualtrics before and very confused!
