概要	Qualitative-dominant case-focused mixed methods design embeds quantitative evidence inside a primarily qualitative case study framework. The case — a bounded unit such as a school, organization, or community — is examined in depth through qualitative means, while quantitative data serve a secondary, supplementary role. Priority is firmly with the qualitative strand, which drives interpretation and findings.	The concurrent embedded mixed methods design collects quantitative and qualitative data at the same time, but assigns unequal priority to the two strands: one (usually quantitative) serves as the primary study, while the other (usually qualitative) is nested inside it to answer a supplementary question. The embedded strand does not stand alone; it provides a different perspective on the same phenomenon within a single unified study.
