Which of the following is an example of qualitative data?

Qualitative data refers to non-numeric information that is used to describe qualities or characteristics. It often captures subjective attributes, opinions, and descriptions rather than measurable quantities. Customer complaints serve as a prime example of qualitative data because they reflect individual experiences, sentiments, and perceptions regarding a service or product, providing rich insights into the customer experience.

In contrast, the other options represent quantitative data, which is characterized by numerical values. For instance, the number of rounds played and rounds played by time of day both involve counting specific measurable occurrences. Course maintenance statistics provide observable metrics that can be quantified, such as the number of hours spent on maintenance or the amount of resources used. These forms of data focus on concrete measurements that can be aggregated and statistically analyzed. Thus, the correct identification of customer complaints as qualitative data highlights the distinction between qualitative and quantitative data in business planning.
