概要	A design-based qualitative-priority mixed methods design places qualitative inquiry at the centre of the research, using quantitative data in a supporting, secondary role. The qualitative strand drives the research questions, sampling logic, and interpretive conclusions, while quantitative data — collected concurrently or sequentially — provide supplementary breadth, frequency estimates, or contextual triangulation. This approach is codified in the priority-notation system (QUAL + quan) developed by Morse and elaborated in Creswell and Plano Clark's mixed methods design taxonomy.	Grounded Theory (GT) is a systematic qualitative research methodology in which theory emerges directly from data through iterative analysis, rather than being imposed before data collection. Developed by Barney Glaser and Anselm Strauss in 1967, GT prioritizes generating explanatory frameworks grounded in evidence.
