What are social surveys primarily used for?

Social surveys are primarily used to gather quantitative data using structured methods, which is why the chosen answer is the most appropriate. These surveys typically employ close-ended questions that allow researchers to collect standardized data, making it easier to analyze and compare responses across large populations. The quantitative nature of the data collected enables researchers to identify patterns, correlations, and statistical relationships, providing broad insights that can be generalized to a larger group.

Other methods mentioned, such as collecting qualitative feedback, conducting observations, or analyzing existing literature, do not align with the core purpose of social surveys. While qualitative feedback can be valuable, it usually involves more open-ended questions and subjective data, which diverges from the structured, quantifiable approach of social surveys. Observational methods focus on gathering data through direct observation in natural settings rather than structured questionnaires. Analyzing existing literature is about reviewing and synthesizing previous research rather than actively collecting new data, which again diverges from the primary function of social surveys.
