概要	The equal-weight exploratory sequential mixed methods design is a two-phase research strategy in which an initial qualitative strand explores a phenomenon in depth, and its findings directly inform the construction of a subsequent quantitative strand. Unlike the qualitative-priority variant, both strands carry equal analytic importance: neither serves merely as a supplement to the other. The design is particularly powerful when theory or validated instruments are lacking and researchers must build measurement tools grounded in participants' own frameworks before testing them at scale.	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.
