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 exploratory sequential mixed methods design is a two-phase research framework in which a qualitative phase is conducted first to explore a poorly understood phenomenon, and the findings then inform a subsequent quantitative phase — typically to develop and test a survey instrument, measure a theory, or generalize qualitative insights to a larger population. The qualitative strand guides what is measured; the quantitative strand tests or extends those findings at scale.
