👉 Secondary research involves gathering and analyzing existing information that has already been collected by others, typically from published sources such as academic journals, industry reports, government databases, and company filings. This type of research provides context, background, and insights into a topic or market without the need to conduct primary data collection, making it efficient for validating hypotheses, understanding trends, and identifying gaps in knowledge. Secondary research helps researchers and businesses make informed decisions by leveraging established data, reducing the time and resources needed for initial data gathering.
