I conducted a survey in two different languages (german and english).
The questions and ACA tasks for both are exactly the same except for the "text body".
How can I combine both survey into one analysis so that I have "overall utility values"?
Can I combine the data of both surveys in an excel file? It did not work when I tried but maybe I have to pay attention to a certain thing.
It is really important to me to solve this problem.
Thanks in advance.
Kind regards from Shanghai
