Secondary Data Sources
Secondary data sources refer to the collection of data from sources that have already been collected and analyzed by someone else. In data science, secondary data sources are used to supplement primary data sources, which are collected directly by the researcher. Secondary data sources can include a wide range of data, such as government reports, academic studies, market research reports, and social media data. The use of secondary data sources can save time and resources, as the data has already been collected and analyzed. However, it is important to ensure that the data is reliable and relevant to the research question at hand.
