Introduction
Questionnaires and interview schedules are tools used to collect data in research. Both have different formats and methods of use.
Differences Between Questionnaire and Interview Schedule
| Point | Questionnaire | Interview Schedule |

| 2. Mode | Self-administered | Interviewer-administered |
| 3. Cost | Low-cost | More expensive due to need for trained interviewers |
| 4. Clarification | No help available if respondent doesn’t understand | Interviewer can clarify doubts |
