Which of the following is an example of secondary data?

• A. Data from a system
• B. Focus groups
• C. Questionaries
• D. Experiments

Answer: (A)

Secondary data consists of information that has already been collected by someone else for a purpose other than the current analysis and is reused. Data from a system is secondary because it is generated by routine operations and stored in the organization’s information systems, ready to be pulled for analysis without new data collection. In contrast, focus groups, questionnaires, and experiments involve collecting new information directly from people or observing new trials, which makes them primary data collection methods. Therefore, data from a system is the example of secondary data.
