Abstract

This book presents a structured learning pathway for understanding, designing, conducting, and communicating qualitative, quantitative, and mixed methods research. It is based on teaching materials developed to guide university-level research projects and is complemented by current methodological literature, reporting standards, and principles of scientific integrity. The book is intended for undergraduate and graduate students, faculty members, academic supervisors, and researchers who need to make methodological decisions that are consistent with the research problem rather than simply reproduce predetermined formats. Particular emphasis is placed on the relationship among research questions, objectives, evidence, research design, sampling, instruments, data analysis, and conclusions. The content combines conceptual explanations, examples, decision-making tables, diagrams, and templates. It preserves the practical approach of the qualitative, quantitative, and mixed methods materials developed by the author while updating key concepts such as qualitative saturation, sample size justification, internal consistency, and mixed methods integration in light of specialized methodological literature.
