Final answer:
Surveys are best described as scalable and easy to analyze due to standardized questions, making them well-suited for collecting data from large populations.
Step-by-step explanation:
Surveys are a structured interview method used to collect data from a large number of individuals. They involve asking the same questions to respondents and tabulating and interpreting their answers. Surveys are usually brief and closed-ended, making them easy to analyze due to standardized questions and responses.
Among the descriptors that best characterize surveys, option B, Scalable, is a fitting descriptor. Surveys are designed to collect data from a broad number of respondents efficiently, making them scalable to large populations. Option C, Easy to analyze due to the standardized questions and responses, also accurately describes surveys as the standardized nature of survey questions facilitates easier analysis, typically resulting in both quantitative and qualitative data. While surveys can sometimes provide in-depth information, they are typically not the best method for the most comprehensive data collection, which would be more characteristic of in-depth interviews or case studies. Therefore, option D, Allows for most in-depth information gathering, is not the most accurate descriptor for surveys.
