The previous assignment which we have to hand in was about primary research. We need to do our own research by writing our own questionnaire and interviewing people. In this experience, I really do find that making a survey is not that easy.
Interviewees easily misunderstand what the questions are asking even when you and your groupmates think the question is obvious. Besides, sometimes when we expect the answer to be closed ended for that question, the interviewees actually want to write something for the question as their answer, vice versa.
This leads me to think if there is any techniques which can truly solve this problem. However, I believed that there isnt any. But I think that we can eliminate the chance that these problems happen by understanding more about the psychological aspect of our interviewees.
Especially if we can understand how they perceive things surrounding them, we can do a lot better in designing a suitable and useful questionnaire.
