In research, what type of data is most likely considered qualitative?

The type of data most likely considered qualitative is descriptive insights from interviews. Qualitative data is characterized by its focus on exploring the qualities, attributes, and characteristics of a subject rather than quantifying it. When researchers conduct interviews, they gather rich, narrative information that provides depth and context to the understanding of a phenomenon. This type of data is often open-ended and allows for exploring participants' thoughts, feelings, and experiences in detail.

In contrast, numerical data from surveys, statistical data from experiments, and financial data from reports are primarily quantitative. These types of data are focused on measurement, numbers, and statistical analysis. They aim to provide numerical insights that can be calculated and analyzed mathematically, rather than exploring the qualitative nuances of human experiences.
