概要	A qualitative-dominant concurrent embedded mixed methods design collects qualitative and quantitative data simultaneously, but the qualitative strand carries the primary weight — it drives the research questions, generates the main findings, and frames interpretation. The quantitative strand is embedded within the larger qualitative study to provide supplemental support, context-setting, or triangulation, without displacing the qualitative logic at the core.	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.
