Draw an explanatory sequential mixed methods design diagram with Mermaid flowchart TB syntax. Start with research questions and literature, then the mixed methods design. Use three subgraphs with direction LR inside: Phase 1 Quantitative with developing and piloting the survey, sampling and collecting data, and statistical analysis; Connecting with identifying results that need explaining and selecting interviewees; Phase 2 Qualitative with semi-structured interviews, transcribing and coding, and developing themes. End with integrating both sets of findings and conclusions. Do not use parentheses in node text. Output only the mermaid code block.
