What is meant by secondary data?

Answer and explanation

Correct answer: Data obtained from sources where it was previously collected

Secondary data are data previously collected by another person or organisation and later obtained from an existing source. Examples include books, government reports, research papers, and suitable online databases. Data collected directly from a person for the current purpose are primary data.
