Tóm tắt	A remote survey is a structured data collection method in which respondents complete a questionnaire without the researcher being physically present. Delivered via mail, telephone, email, web platforms, or mobile apps, it enables researchers to reach geographically dispersed samples at relatively low cost. The method is central to social-science, public-health, and organisational research and is codified in Dillman's widely used Tailored Design Method.	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.
