| Muhtasari≠ | A telephone-assisted survey is a structured data-collection method in which a trained interviewer administers a standardised questionnaire to respondents over the telephone, often supported by Computer-Assisted Telephone Interviewing (CATI) software. It combines the efficiency of remote administration with the response-quality advantages of live interviewer guidance, making it widely used in social, public-health, market-research, and political polling contexts. | A face-to-face survey is a structured data collection method in which a trained interviewer meets respondents in person and administers a standardised questionnaire. The interviewer reads questions aloud, clarifies wording when permitted by protocol, and records answers — either on paper (PAPI) or a laptop/tablet (CAPI). This mode consistently achieves higher response rates and better data quality for complex or sensitive questionnaires than self-administered alternatives, and is the reference standard in large-scale population surveys. |
