What is secondary analysis?

Secondary analysis refers to the process of analyzing data that has already been collected by other researchers for a different purpose. This method allows researchers to explore new questions or validate previous findings without the need for new data collection, which can save time and resources. It often utilizes datasets from surveys, experiments, or existing records, enabling insights across various fields such as Social Sciences, public health, and economics. Additionally, secondary analysis can enhance the understanding of trends and patterns over time by leveraging previously gathered information.
