2. DEFINING BUSINESS RESEARCH
METHODS
• Business research is defined as the systematic
and objective process of generating
information for aid in making business
decisions.
• Acquisition of information or knowledge for
professional or commercial purpose to
determine opportunities and goals for a
business.
5. WHAT RESEARCH IS NOT
• Mere data collection
• Mere Literature Review
- Synthesis and analysis
5
6. WHAT IS GOOD RESEARCH
• Purpose clearly defined
• Research process detailed
• Research design thoroughly planned
• High ethical standards applied
• Limitations frankly revealed
• Adequate analysis for decision makers’ needs
• Findings presented unambiguously
• Conclusions justified
• Researcher's experience reflected
7. FALLACIES IN RESEARCH
• Research Objective
• Hypotheses
• Methodology
- type
- sampling
- data analysis
• Interpretation of results
• Overall alignment
8. TYPES OF BUSINESS RESEARCH: BY SOURCE
Primary Collection of data specifically for the problem or
project in hand.
Secondary Based on data previously collected for purposes
other than the research in hand (e.g. published articles,
government statistics, etc.).
11. Deductive Research
Starts with theory,
moves to hypothesis,
observation, and
conclusion
Inductive Research:
Starts with observation
and moves to form a
theory

INDUCTIVE & DEDUCTIVE REASONING
16. Concepts
• Scientific methods and scientific thinking are
based on concepts, the symbols we attach to
bundles of meaning that we hold and share with
others.
• A concept is a generally accepted collection of
meanings or characteristics associated with
certain events, objects, conditions, situations, and
behaviors.
• We invent concepts to think about and
communicate abstractions.
17. Constructs
• We build constructs by combining the simpler,
more concrete concepts, especially when the
idea or image we intend to convey is not
subject to direct observation.
• Higher-level concepts are called constructs.
19. Definitions
• An operational definition is a definition stated
in terms of specific criteria for testing or
measurement.
• Operational definitions may vary, depending
on your purpose and the way you choose to
measure them.
20. Variables
• In practice, the term variable is used as a synonym
for construct, or the property being studied.
• A variable is a symbol of an event, act,
characteristic, trait, or attribute that can be
measured and to which we assign values.
• For purposes of data entry and analysis, we assign
numerical value to a variable based on the
variable’s properties.
• Dichotomous and Continuous Variables
21. Concepts and constructs are used at the
theoretical levels;
variables are used at the empirical level.
24. EXAMPLES
• In a study to determine
whether how long a
student sleeps affects
test scores the
independent variable is
the length of time spent
sleeping while the
dependent variable is
the test score.
• How does service
tenure affect job
performance of an
employee.
Duration of
Sleep
Test Scores
Tenure
Job
Performance
25. Moderator
• A moderator affects the
strength of the relationship
between the independent
and the dependent variable.
Mediator
• A mediating variable
explains the relationship
between the independent
and dependent variable.
• It explains the ‘how’ or
‘why’ there is a relationship
between two variables.
29. Hypotheses
• A hypothesis describes the relationships
between or among variables.
• A good hypothesis is one that can explain
what it claims to explain; is testable; and has
greater range, probability, and simplicity than
its rivals.
30. • As a declarative statement about the
relationship between two or more variables, a
hypothesis is of a tentative and conjectural
nature.
31. Theories
• Sets of interrelated concepts, definitions, and
propositions that are advanced to explain and
predict phenomena are called theories.
• Theories are the generalizations we make
about variables and the relationships among
them.
• In general, theories tend to be complex and
abstract and to involve multiple variables.
32.
33. Models
• Models differ from theories in that models are
analogies or representations of some aspect of a
system or of the system as a whole.
• Models are used for description, prediction, and
control.
• Models differ from theories in that a theory’s role
is explanation whereas a model’s role is
representation.
35. ETHICAL ASPECTS
• Plagiarism
• Informed consent
• Confidentiality/Anonymity
• If there were any findings that refuted the researcher’s hypothesis, did he or she
address these findings?
• If any results were unexpected, did the researcher acknowledge this?
• Did the researcher discuss any explanations for the unexpected effects?
• Did the researcher adequately acknowledge the limitations of the research?
