Abstract: Research design and methodology provide the systematic foundation for conducting scientifically credible research. This chapter presents the fundamental concepts and principles involved in planning, conducting, analysing, and interpreting a research study. It explains research design as the overall framework linking the research problem, objectives, variables, data collection, experimental conditions, sampling, analysis, and interpretation. Various research designs, including exploratory, descriptive, experimental, correlational, historical, and case study designs, are discussed. The chapter further examines quantitative, qualitative, and mixed-method approaches and explains the formulation of research problems, research questions, objectives, and hypotheses. Major aspects of population and sampling, data collection methods, research instruments, measurement, data analysis, reliability, validity, and research quality are also addressed. Particular emphasis is placed on selecting methods that are consistent with research objectives and on ensuring transparency, accuracy, and reproducibility. Ethical considerations, including informed consent, confidentiality, academic integrity, and responsible handling of research data, are also highlighted. Overall, the chapter provides a comprehensive framework for developing systematic, reliable, valid, and ethically responsible research capable of producing meaningful evidence-based conclusions.
