Research design is a detailed plan that outlines data collection, analysis, interpretation, and sampling methods, acting as a roadmap for the research process. It includes quantitative research, focused on numerical data, and qualitative research, centered on attitudes and beliefs. Cross-sectional studies compare different subjects at a single point in time, while longitudinal studies observe the same subjects over time, enabling the establishment of cause-and-effect relationships.
