What distinguishes secondary research from primary research?

Secondary research is distinct because it relies on data that has already been collected and published by others, which can include academic papers, reports, articles, or databases. This existing data can be analyzed to draw insights without the need to gather new data firsthand. Researchers utilize this approach to benefit from the extensive work already done, saving time and resources.

The other options do not accurately describe this distinction. While primary research involves the collection of new, original data tailored for a specific study or inquiry, it isn't inherently faster and easier; it can often be time-consuming and resource-intensive. Additionally, primary research is not exclusively qualitative, as it can also involve quantitative methods. Finally, secondary research is not limited to online sources; it encompasses a wide range of formats and mediums, including print sources, journals, and published studies that may be accessed via libraries or archives.
