What type of data is previously collected for another purpose?

The correct answer is secondary data. This type of data refers to information that has already been collected by someone else for a different purpose than the current research being conducted. Secondary data can come from various sources, such as previous studies, government reports, and historical records. Researchers often use secondary data to leverage existing information, which can save time and resources compared to collecting new data.

Primary data, on the other hand, is information gathered firsthand for a specific research objective. Original data is often used interchangeably with primary data and emphasizes data collected directly in its initial form. Raw data refers to unprocessed data that has not yet been analyzed or altered, regardless of its purpose. In contrast, secondary data has already gone through a collection process, which differentiates it from the other types mentioned.
