Concept
of Research – Meaning, Characteristics and objectives
Introduction: Research is an art of
scientific investigation. Research covers the search for and retrieval of
information for a specific purpose. Research has many categories, from medical
research to literary research. Basically research is a search for truth with
the help of some study, observation, comparison and experiments. It is search
for knowledge with the help of objective and systematic method of finding
solution to a problem.
Meaning of Research: Research in common
man’s language refers to “search for knowledge”. Research is simply the process
of finding solution to a problem after a complete study and analysis of
situational factors.
Research is
purposeful investigation. It provides a structure for decision making. It
provides an analytical framework for the subject matter of investigation. It
establishes the relationship between different variables, especially the
relationship of the dependent variable with the valuable independent variables.
In short, the search for knowledge through objective and systematic method of
finding solution to a problem is research. Research is required because of the
following reasons:
Ø
To identify and find solutions to the problems.
Ø
To help making decisions.
Ø
To develop new concepts.
Ø
To find alternative strategies.
1)
To
identify and find solutions to the problems: Research is required to
understand the problems in depth. For example:
Ø
Why is that demand for a product is falling?
Ø
Why is there a business fluctuation once in
three years?
By identify the problem as above; it is
easy to collect the relevant date to solve the problem.
2)
To help
making decisions: Research is helpful for making the decision. For example:
Should we maintain the advertising budget same as last year? Research will
answer this question.
3)
To find
alternative strategies: Research is helpful to find alternative strategies.
For examples: Should we follow pull strategy or push strategy to promote the
product.
4)
To
develop new concepts.
Definition of Research:
According to P.M. Cook, “Research is an honest, exhaustive,
intelligent searching for facts and their meanings for implications with
reference to given problem. It is the process of arriving at dependable
solutions to problems through the planned and systematic collection, analysis
and interpretation of data. The best search is that which is reliable,
verifiable and exhaustive so that it provides information in which we have
confidence.”
Characteristics of Research: The characteristics
of research are as follows:
1.
Systematic
Approach: Each step must on your investigation be so planned that it lead
to the next step.
2.
Objectivity:
It implies that true research should attempt to find an unbiased answer to the
decision making problem. Its means true research have a pre-planned objective.
3.
Relevancy:
A research should be relevant according to objective and according to
information required for that. It furnishes three important tasks:
a)
It avoids the collection of irrelevant data or information
and saves money and time.
b)
It compares the information to be collected with
researcher’s criteria for action.
c)
It enables to see whether to research is
proceeding in right direction.
Nature of Research: The natures of
research are as follows:
1)
Objectives
& Logical: Research strives to be objective and logical, applying every
possible test to validate the procedure employed, the data collected and the
conclusion reached.
2)
Future
Occurrence: Research emphasizes the development of generalization, principles
of theories that will be helpful in predicting future occurrences.
3)
Courage:
Research some times required courage.
4)
Solve the
Problem: Research is directed towards the solution of a problem. It may
attempt to answer a question to determine the relation between two or more
variables.
5)
Experiences:
Research is based upon observable experience.
6)
Recording
and reporting: Research is carefully recorded and reported.
7)
Expertise:
Research requires expertise; the researcher knows what is already known about
the problem and how others have investigated it.
8)
Collection
of Data: Research involves gathering new data from primary sources or using
existing data for new purpose.
9)
Research
demand accurate descriptions.
Objectives of Research: All researchers
aim at finding answer to questions by applying certain scientific procedures.
Research investigates the truth, which is hidden and tries to find solution to
existing problem which have not been discovered yet. Different research studies
have different purposes depending on nature and type of research. Generally, we
have following categories of objectives of research:
1)
To
investigates a Subject: Research is undertaken in a specific field of
knowledge. It may be pure science or social science; one may be interested in
verifying a fact or principle in any discipline of his choice like physics,
chemistry, botany, commerce or economics. For that matter, every discipline is
a body of knowledge. An activity undertaken to verify or revise these facts or
principles becomes research.
2)
To
collect the data regarding a problem: Research gathers new knowledge or
data from primary or first hand sources. It is not research when on simply
restates what is already known or what has been written. Research endeavors to
research the first hand source of data instead of serving its purpose with the
data available from second hand sources.
3)
To
conduct logical and objective study: Research is logical and objective,
applying every possible test to verify the data collected and the procedure
employed. The researcher eliminates personal feelings and preferences from his
research activity. He works with in the scope and relevance of his data.
4)
To
conduct a systematic inquiry of the subject: Research is said to be a
careful and systematic inquiry. It means that research is a scientific study of
facts.
5)
For
carefully recording, reporting and presenting the facts: Research is
carefully recorded and reported. Every term is carefully defined, all
procedures and described in details, all limiting factors are recognized, all
reference are carefully documented and all results are objectively recorded.
Various
Types of Research
Types of Research: On the basis of the
objectives of the research, we can classify research into following types:
a) Applied Vs. Fundamental Research: Research
can either be applied or fundamental. Applied research aims at finding a
solution for an immediate problem facing a society or an industrial/business
organization, whereas fundamental research is mainly concerned with generalizations
and with the formulation of a theory. Research to identify social, economic or
political trends that may affect a particular institution or the marketing
research are the examples of applied research. Fundamental is mainly concerned
with generalization and with the formulation of theory. Research concerning some natural phenomenon
or relating to pure mathematics are examples of fundamental research.
b) Descriptive Vs. Analytical 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. In social science and business research, we quite often
use the term Ex-post facto research for descriptive research studies. The main
characteristics of this method are that the researcher has no control over the
variable; he can only report what has happened or what is happening. Most
ex-post facto research projects are used for descriptive studies in which the
researcher seeks to measure such items:
Ø
Frequency of Shopping.
Ø
Preference of people etc.
In analytical
research, the researcher has to use facts or information already available and
analyze these to make a critical evaluation of the material.
c) Quantitative Vs. Qualitative Research: Quantitative
research is based on the measurement of quantity or amount. It is applicable to
phenomena that can be expressed in terms of quantity. It is research
methodology that seeks to quantity the data and typically applies some form of
statistical analysis. Quantitative research is structured in nature and
recommends a final course of action. Qualitative research, on the other hand,
is concerned with qualitative phenomenon. Qualitative research is important in
the behavioural sciences where the aim is to discover the underlying motives of
human behaviour. Through such research we can analyze the various factors,
which motivate people to behave in a particular manner or which make people
like or dislike a particular thing.
d) Conceptual Vs. Empirical Research: Conceptual research is related to some abstract
ideas of theory. It is generally used by philosophers and thinkers to develop
new concepts. On the other hand, 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. We can also call it an experimental type of
research.
e) Other types of research: All types of research are variations of one
or more of the above stated approaches, based on either the purpose of
research, or the time required to accomplish research, on the environment in
which research is done, or on the basis of some other similar factors. There
are many other types of research based on their occurrence such as one-time
research, field-setting research, clinical or diagnostic, historical and
conclusion-oriented research etc.
Significance
of Research in Business Decision Making:
The role of
research has greatly increased in the field of business and economy as a whole.
In modern of development three factors increase the interest in a research to
business decision making.
a)
The manager’s increased need for more and better
information.
b)
The availability of improved techniques and
tools to meet this need.
c)
The resulting information overload.
Role of research
in important areas of business through research, an executive can quickly get a
information of the current scenario. The following are the major key areas in which
research play a key role in making effective decisions.
a)
Scientific and Inductive: Research inculcates scientific and inductive
thinking and it promotes the development of logical habit of thinking and
organisation.
b)
Aid to Economics Policy: The role of research in several fields of
applied economics, whether related to business or to the economy as a whole has
greatly increased in modern times. The increasingly complex nature of business
and government has focused attention on the use of research in solving
operational problems. Research as an aid
to economic policy has gained added importance.
c)
Basis for Policies: Research provides the basis for nearly all
government policies in our economic system.
For instance, govt’s budget rest in part on an analysis of the need and
desire of people and on the availability of revenues to meet these needs. The cost of need has to be equated to
probable revenues and this is a field where research is most needed.
d)
Operational and Planning: Research has its special significance in
solving various operational and planning problems of business and
industry. Operation research refers to
application of mathematical, logical and analytical techniques to the solution
of business problems of cost minimization or profit maximization or
optimization problems. Business
budgeting, which ultimately results in a projected profit and loss account, is
based mainly on sales estimates which in turn depend on business research. Thus research replaces intuitive business
decisions by more logical and scientific decisions.
e)
Social Relationship: Research is equally important for social
scientists in solving social relationship and in seeking answers to social
problems. Research in social science is
concerned both with knowledge for its own sake and with knowledge for what it
can contribute to practical concerns.
f)
Other significance of research
Ø
To those student who are to write a master or
Ph.D. thesis, research may mean careerism or a way to attain high position in
the social structure.
Ø
To professional in research methodology, It may
mean a source of livelihood.
Ø
To philosophers and thinkers, it may mean the
outlet for new ideas and insight.
Ø
To literary man and women, it may mean the
development of new styles and creative work.
Ø
To analysts and intellectuals, it may mean the
generalisation of new theories.
Research
Design
The most
significant part that follows the task of defining the research problem is the
preparation of the design of the research project, popularly known as ‘research
design’. A research 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. According to Pauline V Young, “The logical
and systematic planning and directing a piece of research is called research
design”. First, it is the plan that
specifies the sources and types of information relevant to the research
questions. Second, it is strategy or
blueprint specifying which approach will be used for gathering and analysing
the data. Finally, since most business
research studies have time and economic constraint, both time and cost budget
are typically included.
Need for
Research Design: It is needed because it facilitates the smooth sailing of the
various research operations, thereby making research as efficient as possible
yielding maximum information with minimal expenditure of efforts, time and
money. Research design stands for advance planning of the methods to be adapted
for collecting the relevant data and technique to be used in their analysis
keeping in view the objective of the research and the availability of staff,
time and money. A research design
usually involves he consideration of the following factors:
a.
The mean for obtaining information.
b.
The availability and skills of the researcher
and his staff, if nay.
c.
The objective of the problem to be studied.
d.
The nature of the problem to be studied.
e.
The availability of time and money for the
research work.
Characteristics of research design
a)
Objectivity: The findings obtained by the
research should be objective. It is possible by allowing more than one person
to agree between the final scores/ conclusion of the research.
b)
Reliability: If the similar research is carried
out time and again in a similar setting it must give similar result. So the
researcher must frame the research questions to make it reliable and provide
similar outcomes.
c)
Validity: Any measuring device can be said to be
valid if it measures what it is expected to measure and nothing else. To make a
research valid the questionnaire framed before research must be framed
accordingly.
d)
Generalization: The information collected from
given sample must be utilized for providing a general application to the large
group of which the sample is drawn.
Types
of Research Design
Research design
is of four types
a)
Sampling design: In this design the total
population is census and a random sample is taken which denotes the entire
population. There are two types of sampling design:
Ø Probability
Ø Non-probability
b)
Observational design: In this design the
researcher plans how to take data for research.
c)
Operational design: In this deign the researcher
design how the research is going to be operated.
d)
Statistical design: In this design the
statistical tools to use for research are planned by the researcher.
Components or essentials of
a Research Design
Components of a
Research Design are given below
a)
Dependent and Independent Variables: A
magnitude that varies is known as a variable. The concept may assume different
quantitative values, like height, weight, income, etc. Qualitative variables
are not quantifiable in the strictest sense of objectivity. However, the
qualitative phenomena may also be quantified in terms of the presence or
absence of the attribute considered. Phenomena that assume different values
quantitatively even in decimal points are known as ‘continuous variables’. But,
all variables need not be continuous. Values that can be expressed only in
integer values are called ‘non-continuous variables’. In statistical terms,
they are also known as ‘discrete variable’. For example, age is a continuous
variable; whereas the number of children is a non-continuous variable. When changes
in one variable depend upon the changes in one or more other variables, it is
known as a dependent or endogenous variable, and the variables that cause the
changes in the dependent variable are known as the independent or explanatory
or exogenous variables. For example, if demand depends upon price, then demand
is a dependent variable, while price is the independent variable. And if, more
variables determine demand, like income and prices of substitute commodity,
then demand also depends upon them in addition to the own price. Then, demand
is a dependent variable which is determined by the independent variables like
own price, income and price of a substitute.
b)
Extraneous Variable: The
independent variables which are not directly related to the purpose of the
study but affect the dependent variable are known as extraneous variables. For
instance, assume that a researcher wants to test the hypothesis that there is a
relationship between children’s school performance and their
self-concepts, in which case the latter is an independent variable and the
former, the dependent variable. In this context, intelligence may also
influence the school performance.
c)
Control: One of the
most important features of a good research design is to minimize the effect of
extraneous variable. Technically, the term control is used when a researcher
designs the study in such a manner that it minimizes the effects of extraneous
independent variables. The term control is used in experimental research to
reflect the restrain in experimental conditions.
d)
Confounded Relationship: The
relationship between dependent and independent variables is said to be
confounded by an extraneous variable, when the dependent variable is not free
from its effects.
e)
Research Hypothesis: When a
prediction or a hypothesized relationship is tested by adopting scientific
methods, it is known as research hypothesis. The research hypothesis is a
predictive statement which relates a dependent variable and an independent
variable. Generally, a research hypothesis must consist of at least one
dependent variable and one independent variable. Whereas, the relationships
that are assumed but not be tested are predictive statements that are not to be
objectively verified are not classified as research hypothesis.
f)
Experimental and Control Groups: When
a group is exposed to usual conditions in an experimental hypothesis-testing
research, it is known as ‘control group’. On the other hand, when the group is
exposed to certain new or special condition, it is known as an ‘experimental
group’. In the aforementioned example, the Group A can be called a
control group and the Group B an experimental one. If both the groups A and B
are exposed to some special feature, then both the groups may be called as
‘experimental groups’. A research design may include only the experimental
group or the both experimental and control groups together.
g)
Treatments: Treatments
refer to the different conditions to which the experimental and control groups
are subject to. In the example considered, the two treatments are the parents
with regular earnings and those with no regular earnings. Likewise, if a
research study attempts to examine through an experiment regarding the
comparative impacts of three different types of fertilizers on the yield of
rice crop, then the three types of fertilizers would be treated as the three
treatments.
h)
Experiment: An
experiment refers to the process of verifying the truth of a statistical
hypothesis relating to a given research problem. For instance, the experiment
may be conducted to examine the yield of a certain new variety of rice crop
developed. Further, Experiments may be categorized into two types namely,
absolute experiment and comparative experiment. If a researcher wishes to
determine the impact of a chemical fertilizer on the yield of a particular variant of
the rice crop, then it is known as absolute experiment. Meanwhile, if the
researcher wishes to determine the impact of chemical fertilizer as compared to
the impact of bio-fertilizer, then the experiment is known as a comparative
experiment.
i)
Experiment Unit: Experimental
units refer to the predetermined plots, characteristics or the blocks, to which
the different treatments are applied. It is worth mentioning here that such
experimental units must be selected with great caution.
