Which of the following is an example of qualitative data collection?

Open-ended questions are a prime example of qualitative data collection because they allow respondents to express their thoughts, feelings, and opinions in their own words. This form of data collection is designed to gather rich, descriptive information that provides insight into the participant's perspective, rather than confining them to predefined responses.

In contrast, rating scales, multiple-choice questions, and surveys with fixed responses are structured forms of data collection that typically yield quantitative data. These methods restrict answers to specific options, which means they are more suited for collecting measurable data rather than exploring the nuances of individual experiences or opinions. By using open-ended questions, researchers can capture a broader range of ideas and themes that might not emerge through more structured inquiry.
