A survey is a research method that collects data from a sample of people, usually through questionnaires or interviews. It is used to gather information about opinions, behaviours, preferences, and demographics.

Surveys can be conducted online, by phone, by mail, or in person. Good survey design includes clear questions, unbiased wording, appropriate scales, and a representative sample. Surveys are widely used in marketing research, social science, and customer feedback.
