This document discusses research design and provides definitions, types, and key aspects to consider when developing a research design. It defines research design as the plan or framework that guides a research study. The document outlines the need for research design to facilitate efficient research and reliable results. It describes four main types of research design: explanatory, descriptive, diagnostic, and experimental. For each type, it provides a brief explanation of its characteristics and goals. The document concludes by listing some advantages of developing an effective research design such as consuming less time and ensuring a systematic research process.

2. Research Design
• A research design is the plan of a research study.
• Research design is the framework that has been created to seek answers to research
questions.
• 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.

3. Definitions of Research Design
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.
According to Green and Tull
 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.

4. Need for Research Design
• Research design is needed because it facilitates the smooth sailing 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.
• For example, economical and attractive construction of house we need a blueprint
(or what is commonly called the map of the house) well thought out and prepared by
an expert architect, similarly we need a research design or a plan in advance of data
collection and analysis for our research project.
• 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.

5. The Need for Research Design ....
• 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.

6. The Function of a Research Design ...
• It 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

7. An effective research design should include ...
• 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.

8. The Design decisions including 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?

9. Types of Research Design
1. Explanatory research Design
2. Descriptive research design
3. Diagnostic research design
4. Experimental research design

10. Explanatory Research design
• In explanatory research design a researcher uses his own imagination and
idea.
• It is based on the researcher personal judgement and obtaining
information about something.
• He is looking for the unexplored situation and brings it to the eyes of the
people.
• In this type of research there is no need of hypothesis formulation.

11. Descriptive Research Design
• In descriptive research design a researcher is interested in describing a particular
situation or phenomena under his study.
• It is a theoretical type of researcher design based on the collection designing and
presentation of the collected data.
• Descriptive research design covers the characteristics of people, materials, socio-
economic characteristics such as their age, education, marital status and income
etc.
• The qualitative nature data is mostly collected like knowledge, attitude, beliefs and
opinion of the people.
• E.g.. Of such designs are the newspaper articles, films, dramas and documentary
etc.

12. Diagnostic Research Design
• Here researcher wants know about the root causes of the problem. He describes the
factors responsible for the problematic situation. It s a problem solving research
design that consists mainly:
• Emergence of the problem
• Diagnosis of the problem
• Solution for the problem and
• Suggestion for the problem solution.

13. Experimental Research Design
• In this type of research design is often uses in natural science nut it is different in
social sciences.
• Human behavior cant be measured through test-tubes and microscopes. The social
researcher use a method of experiment in that type of research design.
• One group is subjected to experiment called independent variables while others is
considered as control group called dependent variable.
• The result obtained by the comparison of both the two groups. Both have the cause
and effect relationship between each other.

14. Advantages of Research design
• Consumes less time.
• Ensures project time schedule.
• Helps researcher to prepare himself to carry out research in a proper and a systematic
way.
• Better documentation of the various activities while the project work is going on.
• Helps in proper planning of the resources and their procurement in right time.
• Provides satisfaction and confidence, accompanied with a sense of success from the
beginning of the work of the research project.
