Which term refers to information collected earlier by others and used later by a sociologist?

• A. Official Statistics
• B. Primary Data
• C. Non-official Statistics
• D. Secondary Data

Answer: (D)

Secondary data refers to information that someone else collected in the past for a purpose other than your current study, and which you then use to explore your own questions. It saves time and resources because the data already exist, and you can analyze it to look for patterns, trends, or to test ideas. Examples include official statistics from government agencies, prior research reports, census data, and published datasets. You just need to check that the data fit your aims, are reliable, and that the way they were collected aligns with your research needs. This broad term covers data like official statistics, but it isn’t limited to them, whereas primary data would be information you gather yourself.
