Secondary data analysis refers to the analysis of existing data collected by others. Secondary analysis affords researchers the opportunity to investigate research questions using large-scale data sets that are often inclusive of under-represented groups, while saving time and resources.
Secondary data (also known as second-party data) refers to any dataset collected by any person other than the one using it. Secondary data sources are extremely useful. They allow researchers and data analysts to build large, high-quality databases that help solve business problems.

What is secondary data analysis? Secondary analysis is any form of research that relies on or uses previously conducted research for the purposes of a new study. If existing data is cited or previously conducted studies help to achieve a new outcome, it’s secondary analysis.
Researchers conducting secondary data analysis commonly analyse data from the same dataset multiple times throughout their careers. However, prior knowledge of the data increases risk of bias, as prior expectations about findings could motivate researchers to pursue certain analyses or questions.
