The most common qualitative data collection method varies depending on the context of the research, but interviews are often considered one of the most widely used methods. Interviews allow for in-depth exploration of individual perspectives and experiences, making them valuable for gathering rich qualitative data.
Focus groups are also popular, especially when researchers want to explore group dynamics and a range of opinions on a topic. Observations can be effective for collecting data on behaviors in natural settings but are typically less common than interviews and focus groups for gathering detailed personal insights.
In summary, while all three methods are common, interviews tend to be the most frequently used qualitative data collection method.
