Qualitative data analysis digs into the "why" and "how" of human experiences, using non-numerical information like text and images. It provides deep insights into complex social phenomena, exploring meanings and motivations behind actions. This approach emphasizes context and subjectivity, requiring flexibility in data collection and analysis. Key concepts include coding, thematic analysis, and grounded theory. Common data collection methods range from interviews to ethnography. Preparing data involves transcription, cleaning, and organization. Popular analysis techniques include content analysis and phenomenological approaches. Various software tools aid in managing and analyzing qualitative data.
