Which method of research provides qualitative insights without manipulating variables?

The case study research method is designed to provide in-depth insights into a specific phenomenon, individual, or group, without the manipulation of variables that characterizes experimental research. This method is particularly valuable for exploring complex issues and developing a comprehensive understanding of contextual factors that influence the subject of study.

In case studies, the researcher gathers qualitative data through various means such as interviews, observations, and document analysis. This allows for a rich, nuanced exploration of beliefs, experiences, and motivations that might not be captured through quantitative methods. Case studies are often used in fields such as psychology, education, and social sciences to analyze intricate dynamics in real-life settings, offering valuable insights that can inform further research or practice.

In contrast, survey research typically involves collecting quantitative data from a larger sample to identify trends or correlations, while experimental research involves manipulation of variables to determine cause-and-effect relationships. Correlational research, while also non-manipulative, focuses on the relationship between variables rather than delving into the subjective experiences unique to an individual or case, which is the hallmark of case study research.
