Research Means
*Systematic and objective
investigation of a subject or a
problem in order to discover
relevant information.
3. Types of Research
1. Fundamental Research
Known as basic or pure research; seeks to expand the boundaries of knowledge in the
given area.
For example
Development of research methods, propagation of new theories, conduction of
academic research studies.

4. 2. Applied Research
* Known as a decisional research
* Attempts to use existing knowledge for resolving the current problem.
For example
* What consumers will like in next five years
* What are the customer needs, expectations, and problems associated to our
offerings?
* Do they like our after sales services? and so on ...

5. Academic Research
¤ An academic research may be defined
as a process that involves systematic
design, collection, interpretation and
reporting of information needed to
solve specific problems or take
advantage of functional opportunities,
or find new dimensions in the existing
theories.
¤ Academic research is also referred to
as basic or fundamental research.
27 November 2020
5
6. ¤ As a whole, an applied research is driven by the objectives of development,
interpretation, and communication of decision-oriented information.
¤ The basic research also serves in a similar fashion so as to facilitate the
development of new theories or principles, or to add new dimensions in the
existing principles or concepts, or challenge them.

19. Variables
Meaning
Known as a property of proposition being studied
Also known as the constructs of a proposition
A symbol to which we assign numerals or values
Numerical value assigned to a variable is based on its properties
27 November 2020
19
20. Three General Examples of Variables
1. Dichotomous Variables
These variables are so called because they have TWO values, reflecting presence
or absence of a property.
For example: pass or fail, exists or does not exist, employed - unemployed, male -
female, yes - no.
The dichotomous variables can be assigned with a numerical value of ‘0’ or ‘1’ for
analysis purpose.
27 November 2020
20
21. 2. Discrete Variables
These are categorical variables.
For example, the demographic variables race or religion are the examples of
discrete variables.
Religion: Hindu, Islam, Buddhism, and Jain can be assigned numerical values of 1,
2, 3, and 4 respectively.
The numerical values assigned to these variables will be of absolute nature; not
like 3.5, or 4.7.
27 November 2020
21
22. 3. Continuous Variables
These variables take on values with a given range or, in some cases, an infinite
set.
For example, test scores may range from 0 - 100, age may be 2.5 years, present
income of a person could be Rs. 15000, you may disclose your property worth more
than Rs. 500,000,000.

Sample vs. Population
Population = collection of ALL possible
observations
Sample = subset of a population
Random Sample
representative of a population
all observations have equal chance of
being selected
24. Why Do We Use Samples?
Cost
Time
Inaccessibility of the population
Accuracy
Destruction of the observations

26. Sampling Methods
Probability vs. Nonprobability
Probability
members in the population have a known chance (probability) of being selected
into the sample
Nonprobability

29. Data
Meaning
Data are the units, or, numbers, or facts that are generated through observation.
Data can be qualitative as well as quantitative.
Considered as the backbone for the evidence of every findings and decision
alternatives in the research.
27 November 2020

30. Data Objectives
Data objectives are derived from the research objectives and comprise of what we
have observed to be lacking in the example.
Their determination mainly rests on the researcher, to translate what the decision
maker wants into a specific description of the needed data.
27 November 2020
30
31. General Qualities Required
1. The measurement should be relevant and adequate to the problem faced to provide
key guidance in decision making.
2. The data must be accurate in both;
i. Validity: Measure what they are supposed to, and
ii. Reliability: On repeating the same method, should give the same results.
3. Data should be obtained quickly enough at an affordable cost.
27 November 2020
31
32. Nature of Data
1. Facts:
* Include the measurements of anything that actually exists or has
existed.
*Facts, generally describe tangible things, they also can be intangibles.
*They generally originate as the demographic, sociological, psychographic, or
behavioral types.
27 November 2020

33. Nature of Data ...
2. Knowledge:
* That is what people know.
*The information true or false, exists or does not exist, etc.
Example
Consumers awareness about a product or a brand.
27 November 2020

34. Nature of Data ...
3. Opinion:
* How people perceive something.
*What they believe about attitudes.
*The mental sets or predisposition to act in some manner.
Example
Consumer perception regarding good or bad.
27 November 2020

35. Nature of Data ...
4. Intentions:
* The acts that people have in mind to do.
*The expectations of their behavior
Example
Consumer interest upon a certain retailer.
27 November 2020
35
36. Nature of Data ...
5. Motives:
* Internal forces that cause people to behave as they do.
*Motives may be instrumental ideas for identifying the subjects about
which the people will speak freely.
Example
A certain consumer never liking wine.
27 November 2020

37. Functions of Data
1. Causation
2. Pay off
Here, ‘X’ is the causation and ‘Y’ is the pay off.
3. Description: Determination of causal variables in
the sample. E.g.: How many of them are ‘X’.
4. Identification: Identification of the particular
source.
e.g.: The name of person who took an interview, or
made an observation, name, address, and locations
of subjects, etc.
27 November 2020
37
Y = f(X)
‘X’ Causes ‘Y’
38. Types of Data
1. Primary Vs. Secondary
Primary Data
That originate from primary sources and are based on observation or investigation or
direct questioning.
* Observation Method
* Interview Method
* Questionnaires
* Projective Techniques
* Content Analysis
27 November 2020

40. 2. Qualitative Vs. Quantitative
Qualitative Data: Psychological, perceptual, or
conceptual data that is not counted in numbers, rather
coded as ‘good or bad’, ‘interesting or boring’ etc.
Quantitative Data: Number based facts and figures.
Frequency of occurrence.
3. Personal Reporting
Data based on individual observation and reporting.
Can be qualitative as well as quantitative.
27

Can be primary/secondary
Always primary
41. Sources of Data
1. Internal
Data developed or gathered, maintained, and preserved by the organization itself.
MIS is the best source for internal records.
MIS comprises of FOUR major components; Management Research Systems (MRS),
Internal Database Systems (IDS), Management Intelligence Systems (MIS), and
Analytical Information Systems (AIS).
Annual reports, collateral materials, press releases etc.
