Which form of research typically involves direct engagement with the subjects being studied?

Primary research is characterized by direct engagement with the subjects being studied, where researchers collect original data firsthand. This can involve a variety of methods such as interviews, surveys, experiments, and observations. The primary goal of this type of research is to gather specific information that addresses particular questions or hypotheses, enabling a deeper understanding of the subject matter. By interacting directly with participants, researchers can tailor their inquiries to obtain relevant insights that are not available through existing sources, making primary research invaluable in many fields, including business, social sciences, and health.

In contrast, secondary research involves analyzing data that has already been collected by others, while tertiary research focuses on synthesizing and summarizing information from primary and secondary sources. Collaborative research, although it may also involve direct engagement, typically emphasizes cooperative efforts among researchers rather than the direct interaction with subjects inherent in primary research.
