How we did it!
During our project days in November 2016, we prepared a questionnaire for the local population of Mönchengladbach. We discussed how to do and did the questionnaire together. On the second day we did the Questionnaire with the local population on the main shopping street of Mönchengladbach, the Hindenburg Street.
The weeks after we worked on the evaluation of the Questionnaire. This was real hard work!
