Qualitative data collection involves gathering non-numerical information through observation, interviews, and interaction to gain deep insights into specific phenomena. Methods include focus groups, one-on-one interviews, direct observation, document analysis, and open-ended questionnaires. While this approach can provide rich, detailed information and context, it also presents challenges, including subjectivity and bias, limited generalizability, and intensive demands on time and resources. The approach chosen must suit the research’s purpose, context, and nature.
