Which of the following is an example of qualitative research?

Qualitative research focuses on understanding the meaning and experiences behind the data, often through non-numerical methods. A thematic analysis of interviews involves collecting detailed, descriptive data from participants about their thoughts, feelings, and experiences, and then identifying patterns or themes within that data. This approach allows researchers to gain deep insights into complex phenomena such as social behaviors, emotions, or personal narratives, which are not easily captured through quantitative methods.

The other options are examples of quantitative research methods. Surveys measuring anxiety levels might collect data that can be quantified and statistically evaluated. A statistical analysis of test scores involves numerical data and seeks to draw conclusions based on statistical relationships. Similarly, a correlation study of height and weight involves measuring these two variables and examining the numerical relationship between them. These methods primarily focus on quantifying data rather than exploring the depth of human experience and meaning, which is the hallmark of qualitative research.
