Which method is most suitable for qualitative data collection?

The most suitable method for qualitative data collection is case studies. This approach allows for an in-depth examination of a particular instance, organization, or event, enabling researchers to gather rich, detailed information that reflects the complexities of real-life situations. Case studies typically involve multiple data sources, such as interviews, observations, and document analysis, making it ideal for exploring subjects in a holistic manner.

In qualitative research, the goal is often to understand the meanings and interpretations individuals or groups assign to their experiences. Case studies facilitate this by providing context and allowing researchers to capture nuanced insights that may not be possible through more quantitative methods. While surveys can collect qualitative data, they are usually structured and may limit the depth of responses. Experiments tend to focus on quantitative data with controlled variables, and random sampling is a technique primarily used in quantitative studies to ensure representativeness rather than exploring qualitative insights.
