lets say i administered questioners to two different sample groups and i would wish two bring them into stata yet they have different variable content.
It’s possible if only the sampled subjects had the same characteristic or else the data will be biased.
Roy, your only two options in Stata are to merge the datasets or to append them. Int he case of merge, you need a common identifier between the two files. In the case of append, you need all the variables to be identical this process basically adds data from one file to the other.
From your description, it seems to me that you have neither a common identifier, nor are your variables the same, so it doesn't seem to me that your data meets the criteria for either option.
Dear Roy,
İf variables are not same why are you trying to combine two different dataset? If you tell your objective, you can get more accurate answers.
Good luck!!
Dear all,
Once again i thank you for your assistance.
My conclusion from the discussion is i can only merge data sets with similar variables regardless of the target group.
