สรุป	Comparative ethnography is a qualitative research design that conducts in-depth ethnographic fieldwork across two or more sites, groups, communities, or cultural settings in order to generate systematic comparisons. Rather than describing a single community in isolation, it traces similarities, differences, and interconnections across cases, producing theoretically grounded insights that no single site could yield alone.	Multiple-case study design investigates two or more bounded real-world cases using the same research protocol, then compares findings across cases to identify patterns, contrasts, and explanatory insights that a single case could not produce. Developed primarily through Robert Yin's replication logic and Robert Stake's collective case tradition, the approach is particularly powerful when a researcher needs to determine whether a phenomenon occurs under varied conditions or to test an emerging theoretical explanation against rival contexts.
