Key Points

Some of the common errors include:

• Selection bias occurs when individuals or groups in a study differ systematically from the population of interest leading to a systematic error in an association or outcome.
• Asking leading questions that result in biased or false answers, as respondents are prone to simply mimic the words of the interviewer.
• Using varying phrasing or tone of voice when conducting interviews
• Intentional errors, such as cheating and fraudulent data entry.
• Failure to record answers accurately due to error of omission.
• Influencing the response of the respondents due to response error occurs due to different factors, including a questionnaire that requires improvements, misinterpretation of questions by interviewers or respondents, and errors in respondents' statements.
• Failure to establish an appropriate interview environment which can lead to falling in self-confidence of the interview by which he/she might not express him/herself as per the potential

Therefore we can say that the correct answer is (A), (B). (E) only.
