Which of the following can be considered an example of a qualitative research project?

The selection of the option that involves a PhD student analyzing interviews with Somali immigrants about their healthcare perceptions is a clear illustration of qualitative research. Qualitative research focuses on understanding human experiences, perceptions, and the meanings individuals attach to those experiences. In this case, the student is gathering rich, descriptive data through interviews, which allows for in-depth insights into the healthcare perceptions of Somali immigrants.

This type of research emphasizes open-ended questions and the subjective interpretation of data, which enables the exploration of complex social phenomena and helps researchers understand different cultural contexts. By using interviews, the researcher can capture the nuances of participants' attitudes and beliefs, providing a deeper understanding of their experiences within the healthcare system.

In contrast, the other scenarios involve methods that are more quantitative in nature, such as collecting data through structured quizzes or measuring physiological responses, which do not aim to explore subjective experiences in depth. These methods are typically focused on numerical data and statistical analysis rather than on qualitative insights.
