Definition of Scientific Research
Scientific Research focusing on solving problems
and pursues a step by step logical, organized
and rigorous method to identify the problems,
gather data, analyze them and draw valid
conclusions there from.

Why Scientific Research?
This research is not based on hunches, experienceand intuition.It is purposive and rigorous.
Enables all those who are interested in researchingand knowing about the same or similar issues tocome up with comparable findings when data areanalyzed.Findings are accurate and confident. Apply solutions to similar problems.

Cont.
It is more objective.Highlights the most critical factors at the work placethat need specific attention to solve or minimize
problems.Scientific Investigation and Managerial DecisionMaking are integral part of effective problem
solving.It can be applied to both basic and appliedresearch.

Purposiveness The research has to start with a definite aim or purposeThe focus is on increasing the commitment ofemployees to the organization, as this will be beneficial
in many ways An increase in employee commitment will translate intoless turnover, less absenteeism, and probablyincreased performance levels, all of which woulddefinitely benefit the organizationThe research thus has a purposive focus

Rigor
A good theoretical base and a sound methodological
design would add rigor to a purposive study.
Rigor adds carefulness and the degree of exactitude in
research investigations.
Rigorous research involves a good theoreticalfoundation and a carefully thought-out methodology.

Example:
A manager asks 10-12 employees how to increase the
level of commitment. If solely on the basis of their
responses the manager reaches several conclusions on
how employee commitment can be increases, the whole
approach to the investigation would be unscientific. It
would lack rigor for the following reasons:

9/32
1. Based on few employees
2. Bias and incorrectness3. There might be other influences on commitment
which are ignored and are important for a researcherto know
Thus, Rigorous involves good theoretical base andthought out methodology.These factors enable the researcher to collect theright kind of information from an appropriate samplewith the minimum degree of bias and facilitatesuitable analysis of the data gathered.This supports the other six too.

Testability
Scientific research lends itself to testing logically
developed hypotheses to see whether or not the data
support the hypotheses that are developed after acareful study of the problem situation.
Testability thus becomes another hallmark of scientific
research.

Replicability
The results of the tests of hypotheses should besupported again and again when the same type ofresearch is repeated in other similar circumstances.
To the extent that the results are replicated or repeated,we will gain confidence in the scientific nature of ourresearch.In other words, our hypotheses would not have beensupported merely by chance, but are reflective of thetrue state of affairs in the population.

12/32
Example:
The study concludes that participation in decision making
is one of the most important factors that influences the
commitment, we will place more faith and credence in
these finding and apply in similar situations. To the
extent that this does happen, we will gain confidencein the scientific nature of our research.

Precision andCondence
Precision refers to the closeness of the findings
to reality based on a sample.
In other words, precision reflects the degree of
accuracy or exactitude of the results on the basis
of the sample, to what really exists in the
universe.

Precision andCondence
Example: If a supervisor estimated the number of
production days lost during the year due to
absenteeism at between 30 and 40, as against the
actual of 35, the precision of my estimation more
favorably than if he has indicated that the loss ofproduction days was somewhere between 20 and
50.

Precision andCondence
Confidence refers to the probability that our estimations are
correct.
That is, it is not merely enough to be precise, but it is also
important that we can confidently claim that 95% of the time
our results would be true and there is only a 5% chance of
our being wrong.

Precision andCondence
The greater the precision and confidence we
aim at our research, the more scientific is the
investigation and the more useful are the
results.

Objectivity
The conclusions drawn through the interpretation of the
results of data analysis should be objective; that is, they
should be based on the facts of the findings derivedfrom actual data, and not on our own subjective or
emotional values.
The more objective the interpretation of the data, the
more scientific the research investigation becomes.

Generalizability
Generalizability refers to the scope of applicability of theresearch findings in one organizational setting to othersettings.
Obviously, the wider the range of applicability of thesolutions generated by research, the more useful theresearch is to the users.For wider generalizability, the research sampling designhas to be logically developed and a number of otherdetails in the data-collection methods need to befollowed.

Generalizability Example: If a researchers 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, then the
generalizability of the findings to other organizational
settings in enhanced. The more generalizable the research,
the greater its usefulness and value.

Parsimony
Simplicity in explaining the phenomena or problems thatoccur, and in generating solutions for the problems, isalways preferred to complex research frameworks thatconsider an unmanageable number of factors.Economy in research models is achieved when we canbuild into our research framework a lesser number of
variables that would explain the variance far moreefficiently than a complex set of variables that wouldonly marginally add to the variance explained.

Parsimony Parsimony can be introduced with a good
understanding of the problem and the important factors
that influence it.
Such a good conceptual theoretical model can be
realized through unstructured and structured interviews
with the concerned people, and a thorough literature
review of the previous research work in the particular
problem area.

Parsimony For instance, if 2-3 specific variables in the work situation
are identified, which when changed would raise the
organizational commitment of the employees by 45%,that would be more useful be more useful and valuable
to the manager than if it were recommended that he
should change 10 different variables to increase
organizational commitment by 48%.

The Building Blocks of Science inResearch
Deduction and Inductions
Answers to issues can be found either by the
process of deduction or the process of induction, or
by a combination of the two.

Theory Building
Deductive Reasoning The logical process of deriving a conclusion
about a specific instance based on a knowngeneral premise or something known to betrue.
Inductive Reasoning The logical process of establishing a general
proposition on the basis of observation ofparticular facts.

Deduction and Induction
Deductive reasoning : application of a general theory toa specific case. Hypothesis testing
Inductive reasoning : a process where we observespecific phenomena and on this basis arrive at generalconclusions. Counting white swans
Both inductive and deductive processes are often usedin research.

Deduction
Deduction is the process by which we arrive at areasoned conclusion by logical generalization of aknown fact.
27 2009 John Wiley & Sons Ltd.www.wileyeurope.com/college/sekaran
Example: we know that all high performers are highly proficient in their jobs.
If John is a high performer, we then conclude that he is highly proficient in his job

Induction Induction is a process where we observe certainphenomena and on this basis arrive at conclusions.
28 2009 John Wiley & Sons Ltd.www.wileyeurope.com/college/sekaran
In other words, in induction we logically establish ageneral proposition based on observed facts.

Other Types of Research
Case Studies
Action Research

Case Studies Involves in-depth, contextual analyses of similarsituations in other organizations, where the nature anddefinition of the problem happen to be the same asexperienced in the current situation.Case studies usually provide qualitative rather thanquantitative data for analysis and interpretation.Ex. A study of what contributes to the successfulinstallation of a good MIS in organizations similar to theone that is planning to install it, and the practicalapplication of that knowledge would be very functional.

Action Research It is sometimes undertaken by consultants who want toinitiate change process in organizations. Action research methodology is most appropriate while
effecting planned changes.Ex. The vice president of a company wants to introducea new system of bookkeeping that is likely to meet withsome resistance from the accounting department.Based on the past experience in the organization, theVP would like to seek a solution to the problem ofemployee resistance.
