Qualitative Sample Size. Qualitative analyses typically require a smaller sample size than quantitative analyses. Qualitative sample sizes should be large enough to obtain enough data to sufficiently describe the phenomenon of interest and address the research questions. The goal of qualitative researchers should be the attainment of saturation.
