What is the difference between secondary analysis and primary research?
What will be an ideal response?
Secondary analysis refers to analysis of data or information collected by another researcher or organization, including the analysis of data sets collated from a variety of sources to create time-series or area-based data sets. It differs from primary research in that primary research involves the firsthand collection of data or information by the researchers or research team. The data are gathered through the research and did not exist prior to the study. By contrast, secondary analysis uses available data or information collected by others, for similar or different purposes, whether research-oriented or not. Secondary analysis can also be additional analysis of a data set collected by the researcher, but to answer questions other than the one initially studied. Not all secondary data analysis studies involve data from external entities. Since most secondary analysis does not require researchers to have contact with subjects, it is sometimes referred to as nonreactive or unobtrusive research.
