What distinguishes secondary research from primary research?

Secondary research is characterized by its use of existing data that has been previously collected and compiled by others. This type of research leverages information that is readily available through various sources such as journals, reports, or online databases, rather than generating fresh data firsthand.

The primary distinction lies in the nature of the data being utilized—secondary research focuses on existing studies and analyses to draw insights, whereas primary research is about gathering new, original data directly from subjects or through direct observation. This makes secondary research a valuable tool for understanding trends, historical perspectives, and previously established findings without the time and resource investment required for conducting new research.

In this context, the other options do not accurately describe secondary research. Analyzing new data pertains to primary research, while the reliability of secondary research can vary based on source credibility rather than being inherently less reliable. Finally, requiring direct interaction with subjects is a hallmark of primary research methodology, not secondary. Thus, option B correctly highlights the essence of secondary research.
