Hi all,

I have some survey data I am trying to analyze. Identifiers were given but not all participants provided their IDs for the post and follow up surveys. I am trying to find a way to match participants from the pre surveys to the post using demographics (i.e., gender, ethnicity, job title, etc). Does anybody have any ideas on how to do this? We have hundreds of participants so it would be difficult to do it by hand. Any advice is much appreciated!!

Thank you!
