Research - Meaning
• Research refers to a search for
knowledge
• Research as a scientific and systematic
search for relevant information on a
specific topic.
• Research is an art of scientific
investigation.
• Research is actually a voyage of
discovery.
Research - Definition
 According to Redman and Mory define
research as a “systematized effort to gain
new knowledge”.
 According to Clifford Woody research
comprises defining and redefining problems,
formulating hypothesis or suggested
solutions: collecting, organizing and
evaluating data; making deductions and
reaching conclusions; and at last carefully
testing the conclusions to determine whether
they fit the formulating hypothesis.
Research – Objectives
• To gain familiarity with a phenomenon
(occurrence) or to achieve new insights into.
(studies with the object in view are termed as
exploratory or formulative research studies)
• To depict accurately the characteristics of a
particular individual, situation or a group.
(studies with the object in view are known as
descriptive research studies)
• To determine the frequency with which
something occurs or with which it is associated
with something else ( studies with this object
in view are known as diagnostic research
studies)
Research – Objectives
• To test a hypothesis of a causal relationship
between variables (such studies are known as
hypothesis-testing research studies)
Research – Types
• Descriptive Vs. Analytical
• Applied Vs. Fundamental
• Quantitative Vs. Qualitative
• Conceptual Vs. Empirical
• Some other types of Research
Descriptive Research
• Includes surveys and fact finding enquiries of
different kinds. The major purpose of
descriptive research is description of the state
of affairs as it exists at present
• Ex post facto research for descriptive research
studies. The main characteristic of this method
is that the researcher has no control over the
variables, it only report
•What was happened
•Or what is happening
Analytical Research
The researcher has to use facts or
information already available, and
analyze these to make a critical
evaluation of the material.
Applied Research
• Or action research aims at finding a
solution for an immediate problem
facing a society or an
industrial/business organization.
Fundamental Research
• Or basic or pure research is mainly
concerned with generalizations and
with the formulation of a theory.
• Gathering knowledge for knowledge’s
sake is termed pure or basic research
Quantitative Research
• Measurement of quantity or amount.
Qualitative Research
• Is concerned with qualitative
phenomenon.
• This type of research aims at
discovering the underlying motives
and desires, using depth interviews for
the purpose. Other techniques of such
research are word association tests,
sentence completion tests, story
completion tests etc.
Conceptual Research
• Is related to some abstract idea(s) or
theory. It is generally used by
philosophers and thinkers to develop
new concepts or reinterpret existing
one.
Empirical Research
• Relies on experience or observation
alone, often without due regard for
system and theory. It is data-based
research coming up with conclusions
which are capable of being verified by
observation or experiment.
Other types of Research
• One time research:
The research is restricted to a single time
period.
• Longitudinal research:
The research is carried on over several
time periods.
• Field-setting research/laboratory
research / simulation research
Depending upon the environment in
which it is to be carried out
Other types of Research
• Historical research:
Is that which utilizes historical sources like
documents, remains etch to study events or
ideas of the past including the philosophy of
persons and groups at any remote point of
time.
• Conclusion oriented:
A researcher is free to pick up a problem,
redesign the enquiry as he proceeds and is
prepared to conceptualize as he wishes
Other types of Research
• Decision oriented:
Is always for the need of a decision maker
and the researcher in this case is not free to
embark upon research according to his own
inclination. (Ex. operations research)
Research Methods
• May be understood as all those
methods/techniques that are used for
conduction of research. Research methods
or techniques, thus refer to the methods the
researchers use in performing research
oprations.
Research Methods – 3 groups
1. Those methods which are concerned with
the collection of data.
2. Those statistical techniques which are used
for establishing relationships between the
data and the unknowns.
3. Those methods which are used to evaluate
the accuracy of the results obtained.

Criteria of good research
•Good research is systematic
•Good research is logical
•Good research is empirical
(external validity to research
results)
•Good research is replicable
(results to be verified)
Problems encountered by researches in
India
• The lack of a scientific training in the
methodology of research.
• Library management and functioning is
not satisfactory at many places.
• There is also the difficulty of timely
availability of published data from
various government and other
agencies
• There does not exist the code of
conduct for researchers.
Research process
• Define research problem
• Review the literature
Review the concepts and theories
Review previous research finding
• Formulate hypotheses
• Design research (including sample design)
• Collect data (Execution)
• Analyse data (Test hypotheses if any)
• Interpret and report
Define research problem
• A proper definition of research problem will
enable the researcher to be on the track
whereas an ill-defined problems may create
hurdles.
Techniques involved in defining research
problem
1. Statement of the problem in a general way
(pilot study)
2. Understanding the nature of the problem
3. Surveying the available literature
4. Developing the ideas through discussions
5. Rephrasing the research problem
Review of literature
The researcher should undertake extensive
literature survey connected with the
problem. For this purpose, the abstracting
and indexing journals, conference
proceedings, govt. reports, books etc.,
A good library will be a great help to the
researcher at this stage.
Development of working hypotheses
Working hypothesis is tentative assumption
made in order to draw out and test its
logical or empirical consequences.
Research Design
“ A resign design is the arrangement of
conditions for collection and analysis of
data in a manner that aims to combine
relevance to the research purpose with
economy in procedure”.
Research Design
1. What is the study about?
2. Why is the study being made?
3. Where will the study be carried out?
4. What type of data is required
5. Where can the required data be found?
6. What periods of time will the study include?
7. What techniques of data collection will be
used?
8. How will the data be analysed?
9. In what style will the report be prepared?

Determining the sample design
• Way of selecting a sample is known as
sample design.
• All items in any field of inquiry
constitute a “universe” or population.
• A complete enumeration of all items in
the population is known as a censes
inquiry.

• Deliberate sampling, purposive
sampling, judgment sampling.
• Under this method the organizers of the
inquiry purposively choose the
particular units of the universe for
constituting a sample on the basis that
the small mass that they so select out
of a huge one will be typical or
representative of the whole
Probability sampling
• Random sampling or chance sampling.
Under this sampling design every item
of the universe has an equal chance of
inclusion in the sample.
• Tippett’s random table (statisticians)
Complex Probability sampling
• Systematic sampling
• Stratified sampling
• Cluster sampling
• Area sampling
• Multi-stage sampling
• Sampling with probability proportional
to size
• Sequential sampling
Collection of data
• Primary data: those are collected a
fresh and for the first time
• Secondary data: those which have
already been collected by someone else
an which have alredy been passed
through the statistical process
Case study
• Form of qualitative analysis and involves a
careful and complete observation of a social
unit a person, a family, an institution, a
cultural group or even the entire community.
Collection of primary data
• Survey and descriptive researches.
Method of collection of primary data
1. Observation method
2. Interview method
3. Questionnaire
4. Through schedules

Processing and analysis of data
• Processing
1. Editing: detect errors and omissions and
correct these when possible
2. Coding: assigning numerals or other symbols
to answer so that responses can be put into
a limited number of categories or classes.
3. Classification: homogeneous groups if we
are to get meaning full relationships.
4. Tabulation: to arrange the same in some
kind of summarizing and logical order

X2 test
F test
Nonparametric tests
The normality of the population
distribution forms the basis for making
statistical inferences about the sample
drawn from the population. But no such
assumptions are made in case of non
parametric test.
Some important Nonparametric tests
• Test of a hypothesis concerning some single value
for the given data (such as one sample sign test)
• Test of hypothesis concerning no difference among
two or more sets of data (two sample sign test,
Fisher-irwin test, Rank sum test)
• Test of a hypothesis of relationship between
variables (such as rank correlation, Kendall’s
coefficient of concordance and other tests for
dependence)
• Test of hypothesis concerning variation in the given
data (ANOVA Kruskal wallis test)
Some important Nonparametric tests
• Test of a hypothesis concerning some single value

Interpretation and Report writing
• Interpretation refers to the task of drawing
inferences from the collected facts after an
analytical and or experimental study.
Interpretation and Report writing
• Interpretation refers to the task of drawing
inferences from the collected facts after an
analytical and or experimental study.
• If hypothesis is tested and upheld several time, it
may be possible for the researcher to arrive at
generalization i.e., to build a theory,
• Finally the researcher has to prepare the report of
what has been done by him.

Research

  • 1. Research Movement from known to the unknown Session – I Dr. M. Saravanan., MBA., M.Com., Ph.D., Department of Commerce Sri Kumara Gurupara Swamigal Arts College, Srivaikuntam
  • 2. Research - Meaning • Research refers to a search for knowledge • Research as a scientific and systematic search for relevant information on a specific topic. • Research is an art of scientific investigation. • Research is actually a voyage of discovery.
  • 3. Research - Definition  According to Redman and Mory define research as a “systematized effort to gain new knowledge”.  According to Clifford Woody research comprises defining and redefining problems, formulating hypothesis or suggested solutions: collecting, organizing and evaluating data; making deductions and reaching conclusions; and at last carefully testing the conclusions to determine whether they fit the formulating hypothesis.
  • 4. Research – Objectives • To gain familiarity with a phenomenon (occurrence) or to achieve new insights into. (studies with the object in view are termed as exploratory or formulative research studies) • To depict accurately the characteristics of a particular individual, situation or a group. (studies with the object in view are known as descriptive research studies) • To determine the frequency with which something occurs or with which it is associated with something else ( studies with this object in view are known as diagnostic research studies)
  • 5. Research – Objectives • To test a hypothesis of a causal relationship between variables (such studies are known as hypothesis-testing research studies)
  • 6. Research – Types • Descriptive Vs. Analytical • Applied Vs. Fundamental • Quantitative Vs. Qualitative • Conceptual Vs. Empirical • Some other types of Research
  • 7. Descriptive Research • Includes surveys and fact finding enquiries of different kinds. The major purpose of descriptive research is description of the state of affairs as it exists at present • Ex post facto research for descriptive research studies. The main characteristic of this method is that the researcher has no control over the variables, it only report •What was happened •Or what is happening
  • 8. Analytical Research The researcher has to use facts or information already available, and analyze these to make a critical evaluation of the material.
  • 9. Applied Research • Or action research aims at finding a solution for an immediate problem facing a society or an industrial/business organization.
  • 10. Fundamental Research • Or basic or pure research is mainly concerned with generalizations and with the formulation of a theory. • Gathering knowledge for knowledge’s sake is termed pure or basic research
  • 11. Quantitative Research • Measurement of quantity or amount.
  • 12. Qualitative Research • Is concerned with qualitative phenomenon. • This type of research aims at discovering the underlying motives and desires, using depth interviews for the purpose. Other techniques of such research are word association tests, sentence completion tests, story completion tests etc.
  • 13. Conceptual Research • Is related to some abstract idea(s) or theory. It is generally used by philosophers and thinkers to develop new concepts or reinterpret existing one.
  • 14. Empirical Research • Relies on experience or observation alone, often without due regard for system and theory. It is data-based research coming up with conclusions which are capable of being verified by observation or experiment.
  • 15. Other types of Research • One time research: The research is restricted to a single time period. • Longitudinal research: The research is carried on over several time periods. • Field-setting research/laboratory research / simulation research Depending upon the environment in which it is to be carried out
  • 16. Other types of Research • Historical research: Is that which utilizes historical sources like documents, remains etch to study events or ideas of the past including the philosophy of persons and groups at any remote point of time. • Conclusion oriented: A researcher is free to pick up a problem, redesign the enquiry as he proceeds and is prepared to conceptualize as he wishes
  • 17. Other types of Research • Decision oriented: Is always for the need of a decision maker and the researcher in this case is not free to embark upon research according to his own inclination. (Ex. operations research)
  • 18. Research Methods • May be understood as all those methods/techniques that are used for conduction of research. Research methods or techniques, thus refer to the methods the researchers use in performing research oprations.
  • 19. Research Methods – 3 groups 1. Those methods which are concerned with the collection of data. 2. Those statistical techniques which are used for establishing relationships between the data and the unknowns. 3. Those methods which are used to evaluate the accuracy of the results obtained.
  • 20. Research Methods – Types Methods Techniques Library research 1. Analysis of historical records 2. Analysis of documents Recording notes, content analysis. Reference and abstract guides, contents analysis Field research 1. Non-participant direct observation 2. Mass observation 3. Mail questionnaire 4. Personal interview Observational behavioral scales Use tape recorder. With open ended and close ended questions Laboratory research Small group study of random behavior and role analysis Use audio video recording devices, use of obervers.
  • 21. Criteria of good research •Good research is systematic •Good research is logical •Good research is empirical (external validity to research results) •Good research is replicable (results to be verified)
  • 22. Problems encountered by researches in India • The lack of a scientific training in the methodology of research. • Library management and functioning is not satisfactory at many places. • There is also the difficulty of timely availability of published data from various government and other agencies • There does not exist the code of conduct for researchers.
  • 23. Research process • Define research problem • Review the literature Review the concepts and theories Review previous research finding • Formulate hypotheses • Design research (including sample design) • Collect data (Execution) • Analyse data (Test hypotheses if any) • Interpret and report
  • 24. Define research problem • A proper definition of research problem will enable the researcher to be on the track whereas an ill-defined problems may create hurdles.
  • 25. Techniques involved in defining research problem 1. Statement of the problem in a general way (pilot study) 2. Understanding the nature of the problem 3. Surveying the available literature 4. Developing the ideas through discussions 5. Rephrasing the research problem
  • 26. Review of literature The researcher should undertake extensive literature survey connected with the problem. For this purpose, the abstracting and indexing journals, conference proceedings, govt. reports, books etc., A good library will be a great help to the researcher at this stage.
  • 27. Development of working hypotheses Working hypothesis is tentative assumption made in order to draw out and test its logical or empirical consequences.
