Is this the way
through which
we acquiretruth..???
after liberalisation, the GNP
is distributed in the favour of
those who have higher propensity to
import and as a result, the
production and the employment
abroad have increased at the cost
of domestic production and
employment. This is also one of
the important reason of recession
in India

QUESTIONING
o BASED UPON WELL ACCEPTED PRINCIPLES OF
LOGIC
o SELF - CORRECTING IN NATURE

Something to think over
The method for scientific investigation is
nothing butthe expression of the necessary
mode of working of the human mind. It is
simply the mode at whichall phenomena are
reasoned about, rendered precise and exact.
We Are All Scientists by T.H. Huxley in Darwiniana (1863)

Whats the most important underlying
philosophy behind scientific knowledge?
Keep the process of knowing authentic
and scientific, the truth with be authentic
and scientific!!!

verywhere our knowledge is incomplete and problems are waiting to be solved.
We address the void in our knowledge, and those unresolved problems,
By asking relevant questions and seeking answers to them.
The role of research is to provide a method for obtaining those answers
By inquiringly studying the facts, within the parameters
Of the scientific method.

Management-research question hierarchy is an easy approach
to identify the research problem from the management dilemma
consisting of hierarchal steps, as follows-
7/31/2019 1Research Methodology - 1
32/45
Management Dilemma- What are the symptoms that cause
management concern?
What environmental stimuli raise
management interest?
Declining sales
Management Question- How can management eliminate the negative
symptoms?
How can management fully capitalize an
opportunity?
How can the sales be improved?
Research Question(s)- What plausible courses of action are available
to management to correct the problem or take
advantage of the opportunity, and which should
be considered?
Should an incentive commission based scheme
be introduced?
Should the level of advertising be increased?
Should the product formula be modified overdifferent regions?
Investigative questions- What does manger need to know to choose the
best alternative?
What is the likelihood that current customer
satisfaction will decrease?
What is the likelihood that the salesperson will
feel motivated by differential compensation
scheme?
Measurement questions- What should be asked or observed to obtain the
manager needs?
Ratings on level of concern on
Lack of predictability of pay
Increased internal compensation
Measures on current image of product
Management decision- What is the recommended course of action,
given research findings?

Using management-research question hierarchy, developthe same for a management dilemma you face atorganization or for a mega store which is experiencing
declining repeat visits at its new superstore.

Hypothesis
An unproven proposition
Suggests possible solution to a problem
An assumption on which we base our research premises and test in
the light of our findings A tentative explanation for an observation, phenomenon, or
scientific problem that can be tested by further investigation
Something taken to be true for the purpose of argument orinvestigation; an assumption
A hypothesisbecomes a theorywhen there is consistency withobservations/predictions
Manager X has high need for achievement.
Managers of Company Y have high need for achievement.
The government is generating awareness on child labour.
Are women better managers ?

STATISTICAL Hypothesis
A hypothesis is a claim (assumption)about a population parameter: -
population mean or
population proportion
Example: The mean monthly cell phone bill of this city is =
$42
Example: The proportion of adults in this city with cell phones
is = 0.68

Null Hypothesis H0States the claim or assertion to be
testedExample: The average number of TV sets in
U.S. Homes is equal to three
Is always about a population parameter,
not about a sample statistic

Null Hypothesis H0
Begin with the assumption that thenull hypothesis is true
Similar to the notion of innocent untilproven guilty
Refers to the status quo
Always contains = , or sign
May or may not be rejected
7/31/2019 1Research Methodology - 1
38/45
Alternative Hypothesis H1
Is the opposite of the null hypothesis e.g., The average number of TV sets in U.S. homes is not equal
to 3 ( H1: 3 )
Challenges the status quo
Never contains the = , or signMay or may not be proven
Is generally the hypothesis that the researcher istrying to prove

CAUSAL / HYPOTHESIS TESTING STUDIES
EXPLORATORY STUDIES
7/31/2019 1Research Methodology - 1
40/45
EXPLORATORY STUDIESFormulates problem for more precise
investigation
Defines objectives, identifies variables and formulateshypothesis to be studied.
Helps in screening alternatives and discovering new ideas. Techniques generally employed to obtain insights and gain
clearer idea of problem:- Secondary data analysis, Focus Group interview,
Experience Survey, Case Study, Projective Techniques
7/31/2019 1Research Methodology - 1
41/45
DESCRIPTIVE STUDIES
Provides description of phenomenon or characteristicsassociated with subject population
Determines frequency of occurrence of these traits estimates proportions of population having certain
characteristics and discovers associations amongdifferent variables
Techniques generally employed -SECONDARY DATA-examination of records, SURVEY questionnaires,interview, OBSERVATION STUDIES
7/31/2019 1Research Methodology - 1

CAUSAL / HYPOTHESIS TESTINGSTUDIES
Used for establishing functional relationship betweencause and effect variables and testing hypothesispertaining to these relationships.
