Correct Answer Explanation
The most common type of instrument used in surveys is a Questionnaire/Interview Schedule.
Key Points:
- A questionnaire can be self-administered by the respondent or administered by the researcher (enumerator) or trained investigator.
- Questionnaires contain closed-ended (structured) or open-ended (unstructured) questions.
- Closed-ended questions include two-way (Yes/No) and multiple-choice questions.
- Questions should be precise, clear, unambiguous and arranged from general to specific.
Why Other Options Are Wrong
- A: Random number tables are used for random sampling, not as a survey instrument.
- C & D: These are data presentation tools, not data collection instruments.
