الملخص	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 longitudinal survey collects structured questionnaire data from the same individuals or units at two or more distinct points in time. By tracking the same respondents across waves, researchers can distinguish genuine change from stable individual differences, establish temporal ordering between variables, and model trajectories of attitudes, behaviors, or outcomes in ways that a single cross-sectional snapshot cannot support.
