Secondary data is defined as information that has already been collected, processed, and made available by som other person or entity.
Unlike primary data, which is gathered firsthand through direct research methods such as surveys, interviews, or experiments, secondary data is pre-existing.
It may come from a wide range of sources like government publications, academic journals, books, historical records, statistical databases, or even reports from private organizations.
The use of secondary data is common in research because it saves time, effort, and costs that would otherwise be spent on primary data collection.
