How is qualitative data best described?

Qualitative data is best described as data that describes qualities and can be categorized. This type of data is non-numeric and focuses on characteristics, attributes, or properties of a subject. For example, qualitative data might include descriptions of color, taste, or feelings, allowing it to be grouped into categories such as "red," "sweet," or "happy." This categorical nature makes it distinct from quantitative data, which is measured in numerical terms and focuses on quantities.

The other descriptions provided focus more on numeric qualities or fixed values, which are characteristic of quantitative data. Thus, the emphasis on categorizing and describing characteristics aligns perfectly with the definition of qualitative data.
