摘要	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.	The Delphi technique is a structured, multi-round data collection method that harvests and refines expert opinion through iterative questionnaires and controlled feedback. Developed at RAND Corporation in the 1950s, it is designed to converge a dispersed expert panel toward a reliable consensus on complex, uncertain, or future-oriented questions — without the conformity pressures of face-to-face group discussion.	An online survey is a structured data collection instrument hosted on a web platform and completed by respondents via internet-connected devices. It enables large-scale, geographically dispersed data gathering at low cost and with rapid turnaround. Respondents self-administer the questionnaire at their convenience, which reduces interviewer bias and permits automatic data capture. Online surveys are the dominant mode of survey research in social, behavioural, health, and market research today.
