What differentiates primary data from secondary data?

The distinction between primary data and secondary data is fundamentally rooted in their sources and purposes. Primary data refers to information that is collected firsthand by the researcher for a specific research question or objective. This could involve methods such as surveys, interviews, or experiments, where the researcher directly engages with subjects to gather new insights.

On the other hand, secondary data consists of information that has already been collected by someone else for purposes other than the current research project. This data can come from various sources, such as academic journals, government reports, or previous studies, and it is utilized by researchers to draw conclusions or support their research without the need to collect new data.

This understanding clarifies that the correct answer highlights the unique nature of primary data as being specifically gathered for a researcher's current needs, while secondary data is leveraged from existing collections that serve different purposes. The other options mischaracterize the nature of these data types, failing to accurately describe the distinction based on their source and intent.
