Dear Colleagues,
I am trying to design a survey for college students. One of the critical
questions of the survey would be the respective GPAs of the concerned
students. However, I am skeptical if people, especially those with GPAs in
the lower range, would choose to answer this question. And there's a
possibility that many people may answer the questions wrongly. This might
lead to a sample bias and the conclusions of the survey might be all wrong.
Hence, I seek your help on tackling this problem. Please let me know what
you feel about the situation. Are there any books or published articles on
the topic that you know of?
Awaiting your response,
Adarsh Joshi
