সারসংক্ষেপ	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.	A structured interview is a data collection technique in which every participant is asked exactly the same pre-specified questions in the same order, using standardized wording. Because the interview schedule is fixed, responses across participants are directly comparable, enabling quantitative aggregation and statistical analysis. It sits at the most standardized end of the interview continuum, between the self-administered questionnaire and the semi-structured interview.	A survey is a systematic data-collection method in which a standardised set of questions is posed to a sample of respondents to measure attitudes, behaviours, demographics, or other constructs. Surveys can be administered via paper, telephone, online platforms, or face-to-face. They are among the most widely used instruments in social, behavioural, health, and educational research because they can reach large, geographically dispersed samples at relatively low cost.
