Secondary Analysis of Existing Data
In secondary allalysis. researchers use existing material and analyze data that were originally collected by others. Existing data sources include public re cords, official reports of organizations and government agencies, and surveys conducted by researchers in universities and private corporations. Research data gathered from studies are available in data banks. such as the Inter-University Consortium for Political and Social Research, the National Opinion Research Center (NORC), and the Roper Public Opinion Research Center. Other sources of data for secondary analysis are books, magazines, newspapers, radio and television programs, and personal documents. Secondary analysis is referred to as unobtrusil'e research because it has no impact on the people being studied. In Durkheirns study of suicide, for example. his analysis of existing statistics on suicide did nothing to increase or decrease the number of people who actually committed suicide.
