This document discusses and compares qualitative and quantitative research methods. Both approaches can generate and measure data, but differ in their underlying strategies. Qualitative research is exploratory and inductive, using methods like grounded theory, ethnography, phenomenology, and field research to understand phenomena from participants' perspectives. These methods prioritize observation and open-ended interviews over experimental controls. Qualitative research provides rich detail but weaker reliability, validity, and generalizability than quantitative methods. Researchers must consider their goals and the trade-offs of each approach.
