Hi,
My survey consists of two different surveys.
Upon completing the first survey, participants have to come back a day after to complete the remaining part of the survey(different survey link). I will be using Mturk to recruit participants but I am not sure how I should be going about this in terms of tracking participants. When I receive data from both surveys, how do I know, for example, Person A has responded to both surveys? Is IP address the only way to track them?
Any help would be appreciated.
