Secondary time. Common sources of existing secondary

Secondary data is research data that has previously been gathered and can be accessed by researchers. The term contrasts with primary data, which is data collected directly from its source.

Secondary data is used to increase the sampling size of research studies and is also chosen for the efficiency and speed that comes with using an already existing resource. Secondary data facilitates large research projects, in which many research groups working in tandem collect secondary data. The main researcher is then allowed to focus on primary research or particular areas of interest. This division of labor helps researchers learn more in less time.Common sources of existing secondary data include data collected by government public services departments, libraries, internet searches and censuses, such as the United States Census.
