Given that a professor surveys his students about their opinions on how well he taught the course. He puts this survey on the last page of his final exam.
The bias may be there due to the following reasons.
i) Students will answer in general and the feedback will not be sensitive
ii) Some students may be too lazy to fill up the survey.
iii) The answers should be simple and specific otherwise the feedback may not be reliable.
Response/ NonResponse: Some students might be too tired to answer the question or in converse, a student might feel that his or her grade might be reflected on the survey since it is not anonymous, he or she might sugarcoat the answer. (incorrect response bias)
