What is the Merit and demerit of secondary data?

The merit of secondary data lies in its cost-effectiveness and time efficiency, as it allows researchers to access existing information without the need for primary data collection. Additionally, it can provide a broader context and historical perspective that may not be feasible to gather independently. However, a demerit is the potential for outdated or biased information, which can compromise the accuracy and relevance of the analysis. Furthermore, secondary data may not perfectly align with the specific research objectives, limiting its usefulness.
