What is the importance of a research design? Write about the various types of research designs.
A research design is a framework or blueprint for conducting the marketing research project. It details the procedures necessary for obtaining the information needed to structure or solve marketing research problems. In simple words it is the general plan of how you will go about your research.
According to Kerlinger
Research design is the plan, structure and strategy of investigation conceived so as to obtain answers to research questions and to control variance.
A research is the specification of methods and procedures for acquiring the information needed. It is the overall operational pattern or framework of the project that stipulates what information is to be collected from which sources by what procedures.
The function of a research design is to ensure that requisite data in accordance with the problem at hand is collected accurately and economically. Simply stated, it is the framework, a blueprint for the research study which guides the collection and analysis of data. The research design, depending upon the needs of the researcher may be a very detailed statement or only furnish the minimum information required for planning the research project.
To be effective, a research design should furnish at least the following details.
- A statement of objectives of the study or the research output.
- A statement of the data inputs required on the basis of which the research problem is to be solved.
- The methods of analysis which shall be used to treat and analyze the data inputs.
More explicitly, the design decisions happen to be in respect of:
- What is the study about?
- Why is the study being made?
- Where will the study be carried out?
- What type of data is required?
- Where can the required data be found?
- What periods of time will the study include?
- What will be the sample design?
- What techniques of data collection will be used?
- How will the data be analyzed?
- In what style will the report be prepared?
