SCIENTIFIC
METHOD OF RESEARCH & ITS
SPECIAL FEATURES
Research
produces knowledge which
could be used for the
solution of problems as well as for
the
generation
of universal theories, principles and laws.
But all knowledge is not
science. The critical
factor
that separates scientific
knowledge from other ways of
acquiring knowledge is that it
uses
scientific
approach. What is this approach? Or
what is science?
When
most people hear the word
science,
the first image that comes to
mind is one of test
tubes,
computers,
rocket ships, and people in
white lab coats. These
outward trappings are part
of science.
Some
sciences, such as the
natural sciences deal with
the physical and material world.
Some other
sciences
involve the study of people
their beliefs, behavior,
interactions, attitudes, institutions,
and so
forth.
They are sometimes called
soft
sciences.
This is not that their
work is sloppy or lack rigor
but
because
their subject matter, human social
life, is fluid, formidable to observe,
and hard to measure
precisely
with laboratory instruments. The
subject matter of a science (e.g. human
attitudes,
protoplasm,
or galaxies) determines the techniques and instruments (e.g.
surveys, microscopes, or
telescopes)
used by it.
Science
is
a way to produce knowledge, which is
based on truth and attempts to be
universal. In other
words
science is a method, a procedure to produce
knowledge i.e. discovering
universalities/principles,
laws,
and theories through the process of
observation and re-observation.
Observation here implies
that
scientists
use "sensory experiences" for the
study of the phenomena. They use
their five senses,
which
are
possessed by every normal human
being. They not only do the
observation of a phenomenon but
also
repeat the observation, may be several
times. The researchers do so because
they want to be
accurate
and definite about their
findings
Re-observation
may be made by the same
researcher at a different time and place
or done by other
professionals
at some other time or place. All
such observations are made in
this universe where a
normal
professional human being can
go, make the observation and
come back. Therefore we
are
focusing
on this universe not on the
one hereafter. By repeating the
observation, the researchers want
to
be
definite and positive about
their findings. Those who
want to be definite and positive
are often
referred
to as positivists.
The researchers do not leave
their findings into
scattered bits and
pieces.
Rather
the results are organized,
systematized, and made part
of the existing body of knowledge;
and
this
is how the knowledge grows. All
this procedure for the creation of
knowledge is called a
scientific
method,
whereby the consequent knowledge
may be referred to as scientific
knowledge. In this
way
science
refers
to both a system for
producing knowledge and the knowledge
produced from that
system.
Since
the subject matters of the researchers
differ, therefore, we have the
diversification of different
sciences:
broadly natural or physical
sciences and human
sciences.
Important
Characteristics of Scientific
Method
1.
Empirical
Scientific
method is concerned with the realities
that are observable through "sensory
experiences." It
generates
knowledge which is verifiable by
experience or observation. Some of the
realities could be
directly
observed, like the number of students
present in the class and how
many of them are male and
how
many female. The same
students have attitudes, values,
motivations, aspirations, and commitments.
These
are also realities which
cannot be observed directly, but the
researchers have designed ways to
observe
these indirectly. Any reality
that cannot be put to "sensory
experience" directly or
indirectly
(existence
of heaven, the Day of Judgment, life
hereafter, God's rewards for
good deeds) does not
fall
within
the domain of scientific method.

Verifiable
Observations
made through scientific method
are to be verified again by
using the senses to confirm
or
refute
the previous findings. Such
confirmations may have to be made by the
same researcher or others.
We
will place more faith and
credence in those findings and
conclusions if similar findings emerge
on
the
basis of data collected by
other researchers using the
same methods. To the extent
that it does
happen
(i.e. the results are
replicated or repeated) we will gain
confidence in the scientific nature of
our
research.
Replicability, in this way, is an
important characteristic of scientific method.
Hence
revelations
and intuitions are out of the
domain of scientific
method.
3.
Cumulative
Prior
to the start of any study the
researchers try to scan
through the literature and
see that their study
is
not
a repetition in ignorance. Instead of
reinventing the wheel the researchers
take stock of the existing
body
of knowledge and try to build on
it. Also the researchers do
not leave their research
findings into
scattered
bits and pieces. Facts
and figures are to be
provided with language and thereby
inferences
drawn.
The results are to be
organized and systematized. Nevertheless,
we don't want to leave
our
studies
as stand alone. A linkage between the
present and the previous body of
knowledge has to be
established,
and that is how the knowledge
accumulates. Every new crop
of babies does not have
to
start
from a scratch; the existing
body of knowledge provides a huge
foundation on which the
researchers
build on and hence the
knowledge keeps on
growing.
4.
Deterministic
Science
is based on the assumption that all
events have antecedent causes
that are subject to
identification
and logical understanding. For the
scientist, nothing "just happens" it
happens for a
reason.
The scientific researchers
try to explain the emerging phenomenon by
identifying its causes.
Of
the
identified causes which ones
can be the most important?
For example, in the 2006
BA/BS
examination
of the Punjab University 67 percent of the
students failed. What could
be the determinants
of
such a mass failure of
students? The researcher may
try to explain this phenomenon and
come up
with
variety of reasons which may
pertain to students, teachers,
administration, curriculum,
books,
examination
system, and so on. Looking
into such a large number of
reasons may be highly
cumbersome
model for problem solution.
It might be appropriate to tell, of
all these factors which
one
is
the most important, the second
most important, the third
most important, which two in
combination
are
the most important. The
researcher tries to narrow down the
number of reasons in such a way
that
some
action could taken.
Therefore, the achievement of a meaningful, rather
than an elaborate and
cumbersome,
model for problem solution
becomes a critical issue in
research. That is parsimony
which
implies
the explanation with the minimum number
of variables that are responsible
for an undesirable
situation.
5.
Ethical and Ideological
Neutrality
The
conclusions drawn through interpretation
of the results of data analysis should be
objective; that is,
they
should be based on the facts of the
findings derived from actual
data, and not on our
own subjective
or
emotional values. For instance, if we had a hypothesis
that stated that greater
participation in
decision
making will increase
organizational commitment, and
this was not supported by the
results, it
makes
no sense if the researcher continues to argue
that increased opportunities
for employee
participation
would still help. Such an
argument would be based, not on the
factual, data based
research
findings,
but on the subjective opinion of the
researcher. If this was the
conviction of the researcher
all
along,
then there was no need to do the
research in the first place.
Researchers
are human beings, having individual
ideologies, religious affiliations,
cultural differences
which
can influence the research
findings. Any interference of their
personal likings and dis-likings
in
their
research can contaminate the purity of
the data, which ultimately
can affect the predictions
made
by
the researcher. Therefore, one of the
important characteristics of scientific
method is to follow the
principle
of objectivity, uphold neutrality, and
present the results in an unbiased
manner.

Statistical Generalization
Generalisability
refers to the scope of the research
findings in one organizational setting to
other
settings.
Obviously, the wider the range of
applicability of the solutions generated
by research, the more
useful
the research is to users. For instance,
if a researcher's findings that
participation in decision
making
enhances organizational commitment
are found to be true in a
variety of manufacturing,
industrial,
and service organizations, and not
merely in the particular organization
studied by the
researcher,
the generalisability of the findings to
other organizational settings is
enhanced. The more
generalizable
the research, the greater its usefulness
and value.
For
wider generalisability, the research
sampling design has to be logically
developed and a number of
other
details in the data collection
methods need to be meticulously
followed. Here the use of
statistics
is
very helpful. Statistics is device
for comparing what is observed and
what is logically expected.
The
use
of statistics becomes helpful in
making generalizations, which is one of
the goals of scientific
method.
7.
Rationalism
Science
is fundamentally a rational activity, and
the scientific explanation must
make sense. Religion
may
rest on revelations, custom, or
traditions, gambling on faith,
but science must rest on
logical reason.
There
are two distinct logical
systems important to the scientific
quest, referred to as deductive
logic
and
inductive logic. Beveridge
describes them as follows:
Logicians
distinguish between inductive
reasoning (from particular
instances to general
principles,
from facts to theories) and
deductive reasoning (from the general to
the particular,
applying
a theory to a particular case). In
induction one starts from observed
data and
develops
a generalization which explains the
relationships between the objects
observed. On
the
other hand, in deductive reasoning one
starts from some general law
and applies it to a
particular
instance.
The
classical illustration of deductive
logic is the familiar syllogism: "All
men are mortal; Mahmood
is
man;
therefore Mahmood is mortal." A
researcher might then follow
up this deductive exercise
with an
empirical
test of Mahmood's
mortality.
Using
inductive logic, the researcher
might begin by noting that
Mahmood is mortal and observing
a
number
of other mortals as well. He might
then note that all the
observed mortals were men, thereby
arriving
at the tentative conclusion that
all men are
mortal.
In
practice, scientific research involves
both inductive and deductive reasoning as
the scientist shifts
endlessly
back and forth between theory and
empirical observations.
There
could be some other aspects
of scientific method (e.g. self
correcting) but what is
important is that
all
features are interrelated. Scientists
may not adhere to all
these characteristics. For
example,
objectivity
is often violated especially in the
study of human behavior, particularly
when human beings
are
studied by the human beings. Personal
biases of the researchers do contaminate the
findings.
Looking
at the important features of scientific
method one might say that there
are two
power bases of
scientific
knowledge: (1)
empiricism i.e. sensory
experiences or observation, and (2)
rationalism i.e. the
logical
explanations for regularity
and then consequent ional
argumentation for making
generalizations
(theory).
Finally
it may be said that anybody
who is following the scientific procedure
of doing research is
doing
a
scientific research; and the
knowledge generated by such
research is scientific knowledge.
Depending
upon
the subject matter, we try to divide the
sciences into physical or
natural sciences and the
social
sciences.
Due to the nature of the subject matter of the social
sciences, it is rather very difficult to
apply
the
scientific method of research rigorously
and that is why the predictions
made by the social
researchers
are not as dependable as the predictions
made by the natural
scientists.
