সারসংক্ষেপ	A face-to-face structured interview is a data collection method in which a trained interviewer meets each respondent in person and asks a fixed set of questions in a predetermined order, recording responses verbatim or using a closed-response format. It combines the response-rate advantages of personal contact with the standardization of a fixed instrument, making it a cornerstone of large-scale social, health, and policy surveys.	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.
