3. 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.
To 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.

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

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.

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.

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.
