Similarities include creating new knowledge through observation. Differences include purpose, sample size, type of data collected, analysis methods, and generalizability of results. Examples of qualitative methods include case studies, ethnography, content analysis, phenomenology, and grounded theory. Quantitative methods include experimental and survey research.
