To efficiently collect responses from a large user sample, use which method?

• A. Interviews
• B. Surveys
• C. Questionnaires
• D. Sampling methods

Answer: (B)

For gathering input from many users quickly, a survey is the best choice. Surveys are designed to reach a large audience with standardized questions that respondents can answer independently, often online or through other self-administered formats. This setup makes data collection scalable and consistent across many participants.

Interviews, while rich in detail, take more time per person and aren’t as practical for large samples. A questionnaire is the specific set of questions used—often part of a survey—but the method that organizes and scales the process to collect data from many people is the survey. Sampling methods relate to who you include in the study, not the collection process itself.
