Hi.

I have made a survey experiment with two experimental groups. In Stata I now have two variables (var1 and var2) for each group's opinion to a given question (values from 1 to 7).

I now want to create a new third variable that indicates if the respondent is part of group 1 or 2. So all members of var1 should have value 1 and all members of var2 should have value 2.

I guess it is quite simple, but I can't really figure out how to do it.


Hope someone is able to help. Thank you!
