Kaarin in statistics are a type of Secondary data
Data that is gathered by a user other than the main user is referred to as secondary data. Census data, information gathered by government agencies, company records, and data that was initially gathered for other research goals are all common sources of secondary data for social science. Contrarily, primary data are gathered by the researcher who is performing the study.
Secondary data analysis can give larger and higher-quality databases that would be impossible for any individual researcher to acquire on their own, saving time that would otherwise be spent collecting data.
