Research design refers to the overall plan, structure, and strategy conceived to obtain answers to research questions and to control variance. It provides a systematic framework that guides the researcher in collecting, measuring, and analyzing data. A well-prepared research design ensures that the evidence obtained enables the researcher to address the research problem logically and as unambiguously as possible. It acts as a blueprint for the entire research process, integrating different components into a coherent and functional plan. One of the major aspects of a research design is the formulation of research objectives and hypotheses. Clear objectives define what the study seeks to achieve, while hypotheses provide tentative explanations or predictions that can be tested. This aspect ensures that the research remains focused and that data collection is directed toward specific ends rather than being random or unfocused. Another important aspect is the selection of the type of research design. Depending on the nature of the problem, the researcher may choose an exploratory, descriptive, diagnostic, or experimental design. Exploratory design is used when the problem is not clearly defined and aims to gain insights and familiarity. Descriptive design seeks to describe characteristics of a population or phenomenon. Diagnostic design determines the frequency with which something occurs or its association with other variables. Experimental design, on the other hand, aims to test cause-and-effect relationships by manipulating independent variables and controlling extraneous factors. Sampling design is also a crucial
