Which term is used to refer to the information collected from second-hand sources?

The term that refers to information collected from second-hand sources is "Desk Research." This type of research involves gathering existing data that has already been collected and published by others. This can include academic papers, reports, articles, and various types of documentation that contain relevant information. Desk research is often used as a preliminary step when conducting studies or analyses, as it can provide valuable insights without the need for original data collection.

In contrast, primary data refers to information collected firsthand by the researcher for a specific purpose. Field data is a type of primary data gathered from direct observation or experiments conducted in real-world settings. Market Intelligence, while related to the collection and use of data, generally encompasses a broader range of information that includes insights about market trends, competitors, and consumer behavior, which may involve both primary and secondary sources.
