What instrument is used to gather information from a large group of people?

• A. Interview
• B. Survey
• C. Focus group
• D. Questionnaire

Answer: (B)

The instrument used to gather information from a large group of people is a survey. Surveys are designed to collect data efficiently from a diverse audience, often utilizing a series of questions that can be answered in a variety of formats, such as multiple choice or scale ratings. This format allows researchers or organizations to analyze trends, opinions, and behaviors among large populations.

Surveys are particularly effective because they can be distributed widely through various platforms—online, in-person, or by mail—and can quickly gather substantial quantitative data. This capability to reach a broad audience while maintaining a structured format makes surveys an invaluable tool for research in fields like market analysis, social science, and public opinion.

Other options like interviews, focus groups, and questionnaires serve different purposes or involve smaller groups or less structured formats, making them less suitable for collecting large amounts of data efficiently. While questionnaires are closely related to surveys and can be used within them, they are merely the specific set of questions, rather than the overall method of data collection that a survey represents.
