Which source is commonly considered secondary data?

• A. Internet Articles
• B. Focus Groups
• C. Company Newsletters
• D. Statistical Data

Answer: (C)

Secondary data are information that already exists and was collected for another purpose. Company newsletters fit this pattern because they’re created by the company for internal communication, not specifically to answer your current research question. You can read them to gain background, context, or historical insights without having to gather new data yourself. In contrast, collecting fresh opinions and responses from people in a focus group is primary data since it’s data you generate for your study. Internet articles and statistical data are also typically secondary sources, but the newsletter example is a classic, readily available internal source researchers commonly analyze as secondary data.
