A survey is a structured way of asking many people the same questions so their answers can be collected, organized, and analyzed to learn what a group thinks, does, or feels about something. In human research, it usually means a list of questions—on paper, online, by phone, or in person—designed to extract specific data from a particular population.

Basic idea

  • A survey uses a questionnaire (the list of questions) plus a plan for how to distribute it, collect responses, and interpret the results.
  • It is commonly used in social research, marketing, public health, and demography to measure opinions, behaviors, or characteristics of a group.

Common features

  • Same questions for everyone: Each participant is asked an identical set of questions to make results comparable.
  • Multiple delivery modes: Surveys can be done by phone, mail, online forms, or face‑to‑face interviews in public spaces.
  • Quantitative and qualitative data: Questions can be closed-ended (e.g., multiple choice, rating scales) or open-ended (free text), giving both numbers and richer comments.

How a survey works

  1. Define the goal (what you want to learn about a group).
  2. Design the questionnaire and sampling method.
  3. Distribute it to the selected people (the ā€œsampleā€).
  4. Collect, organize, and analyze the responses to draw conclusions about the wider population.

Survey vs. questionnaire

  • A questionnaire is the actual set of questions given to individuals.
  • A survey is the broader process: using questionnaires and possibly other methods to collect, organize, and interpret data from many individuals to generate insights.
