What is Research design?
Research design is the framework of research methods and techniques chosen by a researcher.
The design that is chosen by the researchers allows them to utilize the methods that are suitable for the study and to set up their studies successfully in the future as well.
The function of a research design is to ensure that the evidence obtained enables you to effectively address the research problem logically and as unambiguously as possible.

5. Purpose of Research design To make sure that the conclusions they’ve come to are justified. It means that the research has to confirm or deny the hypothesis. T o broaden the researcher’s understanding of the topic, and to make them more conscious about various places, groups, and settings. Allows the researcher to achieve an accurate understanding of the topic they are working on, and be able to explain the topic to others. 24/03/2022 5

6. The Essential Elements of the Research Design The Essential Elements of the Research Design are: Accurate purpose statement Techniques to be implemented for collecting and analyzing research The method applied for analyzing collected details Type of research methodology Probable objections for research Settings for the research study Timeline Measurement of analysis 24/03/2022 6

7. Basic principles of research design There are some fundamental assumptions in the selection of research design which are given below : Principle of flexibility: Research design should be flexible enough. A researcher may need to improve the design while conducting research because the researcher may face the problem in the real field. To address such problems, the researcher needs to change in design. Thus, the research design should be flexible. Principle of timeliness: Research design should specify the time so that every activity can be completed in time and the researcher can produce a research report in time. 24/03/2022 7

8. Basic principles of research design Principle of replication: Research design that is used by one researcher should be replicable (can be copied) to others whoever likes to do so. It helps to test the design in the different context and helps to theorize the findings. Principle of objective: Research design should be developed in such a way so that it gives the results in a specific and clear form. The results of the research should not be emotional and subjective. Principle of generalizability : Research design is to be developed in such a way that the findings developed from the research can be generalized in the large population even though the findings are developed from the study of the sample. 24/03/2022 8

9. Basic principles of research design Principle of reliability: Research design depends on reliability, consistencies, dependability, and stability. If research gives the same result when same tools are used in the same sample, then such research is considered as reliable research. Research design should be developed in such a way so that it gives consistent results. Validity: Validity is concerned with the integrity of the conclusions that are generated from a piece of research. Research design should specify the variables that can measure the things that they want to measure. 24/03/2022 9
