요약	Case-focused mixed methods design integrates qualitative and quantitative data-collection strands within one or more bounded cases — specific settings, organizations, programs, or individuals. The design harnesses the contextual depth of case study methodology alongside the corroborative or complementary power of mixed data types, enabling researchers to build rich, multi-faceted accounts of complex phenomena situated in real-world contexts.	Multilevel mixed methods design is a research approach that collects and integrates both quantitative and qualitative data at two or more distinct levels of a social or organizational hierarchy — for example, individuals nested within classrooms, classrooms within schools, or patients within healthcare teams. By pairing quantitative measurement of outcomes at one level with qualitative exploration of meaning at another, researchers gain a richer, more complete picture than either strand alone could provide.
