What type of data is referred to as qualitative data?

Qualitative data refers to information that is categorical, describing qualities or characteristics rather than providing numerical values. It encompasses subjective attributes such as colors, names, labels, or any descriptors that convey the nature of an object or phenomenon. This type of data is often collected through interviews, surveys, or observations and is useful for understanding concepts, opinions, or experiences.

The other options suggest different types of data: numerical data is quantitative and measured on a scale, which falls under the category of quantitative data; data derived from automated systems typically refers to structured data generated by machines or software, often quantitative; and experimental data involving controlled variables pertains to scientific experiments aimed at establishing cause-and-effect relationships, primarily focusing on numerical outputs rather than subjective characteristics.
