It incorporates the blueprint for the collection, measurement, and analysis of data. It helps to allocate the limited resources by posing crucial in methodology. It is the plan and structure of investigation so conceived as to obtain the answer to research questions. The plan is the overall program of the research. It cycles from problem selection, measurement tools, data collection, selection of methods for the analysis of data, draw conclusions, and generalization of findings based on the availability of resources and tools.
It is an overall plan of completing the research work. It presents works of research serially from the beginning to the end in a logical way. Some definitions of research design are given below:
According to Kerlinger F.N., “Research design is the plan, structure and strategy of investigations conceived so as to obtain answer of research questions and to control variance.”According to C.R. Kothari, “Research design is the conceptual structure within which research is conducted. It constitutes the blue print for the collection, measurement and qualities of data.”
From the analysis of the above definitions, the following facts are found in the research design.
- It is a framework of research that helps to collect, measurement and analysis of data.
- It helps to select research methods considering limited resources.
- It is a plan and structure to find out the solution of the problem. It incorporates the framework for hypothesis development and analysis of data.
- Research design expresses both the structure of the research problem, the framework, organization or configuration of the relationship among variables of a study, and the plan of the investigation used to obtain empirical evidence on those relationships.
- It is a road map to start the process and conclude the research work.
