Which of the following describes a set of responses categorized for a single case?

A set of responses categorized for a single case is best described as a data record. In the context of data management, a data record represents one complete set of information corresponding to a single subject or instance. For example, in a database, a record might contain all the details about a specific individual, such as their name, age, address, and any other relevant responses or data points collected about them.

Data fields refer to individual pieces of data within a record, like a single characteristic (e.g., just the person's name or age). Data entry refers to the act of inputting data into a system, not the organized collection of information per case. A data file generally refers to a collection of records stored together, often encompassing multiple cases, rather than just one, making it broader in scope than what the question specifies. Therefore, identifying a single case's responses as a data record captures the essence of the compiled information effectively.
