Which method uses observations and un-measurable qualities for research analysis?

Qualitative research is the method that employs observations and un-measurable qualities for research analysis. It focuses on understanding human behavior, emotions, and experiences through various forms of data such as interviews, focus groups, and open-ended surveys. This approach allows researchers to gain insights into complex phenomena that cannot easily be quantified, making it ideal for exploring the nuances of social interactions and cultural contexts. The richness of qualitative data provides depth and context to findings, enabling a more comprehensive understanding of the research subject.

In contrast, quantitative research relies on numerical data and measurable variables, delivering statistical analysis rather than in-depth insights. Descriptive research aims to describe characteristics or functions without necessarily addressing causes or correlations, making it less focused on the qualitative aspects. Reflective research typically emphasizes the process of reflection on experiences or practices, which may incorporate qualitative elements but does not fundamentally focus on un-measurable qualities in the same way that qualitative research does.
