What type of data is concerned with subjective opinions and descriptions?

Qualitative data is concerned with subjective opinions and descriptions because it captures non-numeric information that can be used to understand concepts, thoughts, or experiences. This type of data emphasizes the meaning and characteristics associated with the subject matter rather than focusing on numbers or statistics. It is often collected through methods such as interviews, focus groups, or open-ended survey questions, allowing for a rich and detailed understanding of the topic being studied.

In contrast, quantitative data consists of numerical values that can be measured and statistically analyzed. Secondary data refers to information that has already been collected by someone else, while primary data involves original data collection for a specific research purpose. Each of these other types of data serves different objectives and methodologies, but it is the qualitative data that specifically addresses subjective perceptions and descriptions.
