What research method is focused on understanding human behavior from the subject's viewpoint?

The choice of qualitative research is accurate because this method is designed specifically to explore and understand human behavior and experiences from the perspectives of the subjects themselves. Qualitative research prioritizes the meanings that individuals ascribe to their experiences, allowing for a deeper insight into their thoughts, feelings, motivations, and social contexts. This approach often involves open-ended interviews, focus groups, and observations, where the goal is to gather rich, descriptive data that can illuminate complex social phenomena.

In contrast, the other research methods listed often emphasize different objectives. Outcome-based research typically evaluates the effectiveness of programs or interventions through measurable outcomes rather than subjective experiences. Action research focuses on solving a specific problem or improving practices within a community or organization, often involving direct participation from stakeholders, but it may not always center on personal viewpoints. Experimental research, on the other hand, is characterized by controlled experiments to test hypotheses, which often requires a more objective and quantitative approach rather than capturing the nuanced, subjective experiences of individuals. Thus, qualitative research stands out as the methodology best suited for understanding human behavior from the subject's viewpoint.
