What is highlighted by 'secondary research'?

Secondary research focuses on the collection of existing information that has already been gathered and published by others. This can include a wide range of sources such as books, articles, reports, and databases that have previously been compiled for other purposes. By utilizing these existing resources, researchers can gain insights into their subjects without the need to conduct new experiments or gather original information themselves.

This approach is valuable for providing context, supporting arguments, and identifying trends based on previously established data, making it an essential component of thorough research practices. It enables researchers to leverage the work of others to inform their own analyses or understandings of a topic while saving time and resources compared to generating new data from scratch.
