Which of the following is an example of secondary data?

• A. Surveys Of Customers
• B. Internal Sales Data From Your Own Company
• C. Focus Group Notes
• D. Internet Articles

Answer: (D)

Secondary data is information that already exists and was collected for a purpose other than your current analysis. Internet articles fit this because they’re produced by others for readers in general, not specifically for your project, and you’d reuse them as background or context rather than as data you gathered yourself.

In contrast, surveys of customers are gathered directly from people for your study, making them primary data. Internal sales data from your own company is data you generated through your own operations, also primary. Focus group notes come from a study you conducted, so they’re primary as well.

So the example of secondary data is internet articles.
