Which method involves direct interaction with the subjects to gather information?

The method that involves direct interaction with the subjects to gather information is qualitative research. This approach emphasizes collecting in-depth, subjective data and understanding the experiences, opinions, and emotions of individuals. By interacting directly with subjects through interviews, focus groups, or observations, researchers can gain rich insights into the participants' perspectives.

Qualitative research is particularly valuable when exploring complex social phenomena, as it allows for the exploration of themes and patterns that may not emerge through quantitative methods. This method fosters a deeper understanding of the context and motivations behind behaviors and decisions, making it effective for gathering nuanced information directly from individuals.

In contrast, although methods like surveys and field research may involve interaction to varying degrees, they often prioritize structured data collection or observational techniques, which do not capture the same level of personal perspective as qualitative research.
