Assess graduate-level understanding of core concepts and design frameworks for integrating qualitative and quantitative methods in mixed-methods research, including purposes and rationales for mixing, common typologies (convergent, explanatory sequential, exploratory sequential, embedded), points and strategies for integration (design, data collection, analysis, interpretation), sampling and weighting decisions, validity/trustworthiness concerns (triangulation, complementarity, integration-related validity), data transformation and joint displays, and practical and ethical challenges; require justification of appropriate design choices for given research scenarios.
