What is Research Design? What are Research Design Purposes?
Research design stands for advance planning of the methods to be adopted for collecting the relevant data and the techniques to be used in their analysis.
What are research design purposes? Research design is needed because it facilitates the smooth conducting of the various research operations, thereby making research as efficient as possible yielding maximal information with minimal expenditure of effort, time and money. Research design has a significant impact on the reliability of the results obtained. It thus acts as a firm foundation for the entire research.
Like an architect prepares a blue print before he approves a construction – in the same way researcher makes or prepares a plan or a schedule of his own study before he starts his research work. This helps the researcher to save time and also save some of his crucial resources.
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?
The Importance of Research Design
The importance of research design is as follows:
- It reduces inaccuracy;
- Helps to get maximum efficiency and reliability;
- Eliminates bias and marginal errors;
- Minimizes wastage of time;
- Helpful for collecting research materials;
- Helpful for testing of hypothesis;
- Gives an idea regarding the type of resources required in terms of money, manpower, time, and efforts;
- Provides an overview to other experts;
- Guides the research in the right direction.
Write the factors that are considered for good research design
Research design actually does not tell us precisely regarding what to do but it suggests us how to do and in what should be the flow of activities. Though it is a framework or set of action plan, it cannot be rigid. It is always open for necessary amendment during the course of action. Good research design should fulfill the following features:
- A good research design provides well developed guidelines for entire research steps.
- Research design must be based on research objective(s) and synchronize with the purpose of the research problem.
- Research design should cover the data collection and analysis technique properly.
- A good research design minimizes bias and maximizes the reliability of the data collected and analyzed.
- A design which includes most appropriate techniques of sample selection to form an appropriate sample.
- A design which yields maximum information and provides an opportunity for considering different aspects of a problem is considered to be the most appropriate efficient design.
- A design which gives the smallest experimental error.
- A good research design includes robust validity analysis for the results.
- Generalization is one of the key characteristics of research design. Design should has generalizable feature.
- The outcome of research design should be applicable to a population and not just a restricted sample.
