Qualitative research employs various strategies for data collection and analysis that differ from quantitative methods. It focuses on understanding participants' perspectives in natural settings and emergent design. There are five key characteristics: natural setting, researcher as instrument, multiple sources, participants' meanings, and emergent design. Common strategies include narrative research, phenomenology, ethnography, case study and grounded theory. Data collection involves observations, interviews, documents and audiovisual materials. Analysis includes coding, identifying themes, and interpreting the overall meaning of the findings. Validity strategies help ensure accuracy and reliability. The qualitative write-up uses thick description, quotes, and narrative form.
