What type of data is referred to as qualitative data?

Qualitative data refers to information that describes characteristics or qualities that cannot be quantified numerically. This type of data is primarily expressed through words, such as descriptions of colors, shapes, opinions, or categories. For example, if you were to record people's feelings about a product using terms like "satisfied," "neutral," or "dissatisfied," that would be collecting qualitative data.

The other options highlight different aspects of data types. The first option describes quantitative data, which involves measuring and expressing information as numbers. The third option also relates to quantitative data, emphasizing data that can be counted, like the number of students in a classroom. The fourth option pertains to data that involves measurements, which again points to quantitative data focused on numerical values and physical quantities. Thus, the correct choice accurately reflects the nature of qualitative data as it relates specifically to descriptive, non-numerical information.
