Which of the following is a source of secondary data?

• A. Primary data
• B. Government publications
• C. Surveys designed for a new study
• D. Experiments

Answer: (B)

Secondary data are information that has already been collected by someone else for a purpose other than your current project. Government publications fit this well because they are produced by government bodies to publish official statistics, reports, and policy information, which researchers can reuse for their own analyses. In contrast, the other options involve data you would gather yourself for your specific study—surveys designed for a new study and experiments are collected directly to answer your particular questions, so they’re primary data. Using government publications as a secondary data source lets you access broad, established data quickly and cheaply, though you’d still consider whether the figures are recent and directly relevant to your research.
