Establishing a conceptual, or theoretical
understanding about something to be promoted as
part of disciplinary studies.
For example, development of a theory in public
health.
Investigation on a problem refers to …
Assessing, diagnosing, exploring, or evaluating
various facets pertaining to a management problem.
For example, what percentage of first time

7. Types of Research
Basically, there are only two types of research
a.Fundamental Research
b.Applied Research

8. 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.

9. Applied Research
Known as a decisional research
Attempts to use existing knowledge for resolving
the current problem.
For example?
What are the customer needs, expectations, and
problems associated to our offerings?
How did the general public like the prevailing
governance system?

10. Lets repeat it again…
¤A research may be considered as a
systematic and objective
investigation that involves
systematic design, collection,
preparation, interpretation and
reporting of information needed to
solve specific problems or promote
a domain of learning.

33. 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.
[email protected]
33

34. 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.

35. 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.
[email protected]
35

36. 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.
[email protected]
36

37. 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.
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.
[email protected]
37

38. 4. Intentions:
The acts that people have in mind to do.
The expectations of their behavior
Example: Consumer interest upon a certain retailer.
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.

39. 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.

39
Y = f(X)
‘X’ Causes ‘Y’

40. 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
[email protected]
40

41. 1. Primary Vs. Secondary
Secondary Data
That originate from secondary sources.
Data already available, collected and analyzed by
someone else.
* Publications
* Books
* Journals
* Magazines and Newspapers
* Reports
* Collateral Materials
* PR Messages
[email protected]
41

42. 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.
[email protected]
42
Can be primary/secondary
Always primary

43. 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.
[email protected]
43
Primary

44. 2. External
* Data generated from the published reports of
various bureaus, and public surveys.
Example:
EDIFY International conducting a salt consumption
behavior research study in Nepal, and the same
report findings to be used in other related future
researches.
Use of CBS - Nepal reports for various research
purposes.
[email protected]
44
Secondary

45. 1. Literature Reviews
* A secondary method of data collection.
* Facts gathered in the basis of reviews of various
publications, articles, journals, books, collateral
materials, reports, etc.
* Useful in providing the evidence to the results of
the primary observation.
* Mostly used in understanding the theoretical
phenomenon.
* Very essential in qualitative studies.
[email protected]
45

46. 2. Census
* Census represents the study of universe.
* Mostly conducted by the governments in long
periodical basis.
* Each and every component of the population is
the subject of the study.
* Most costly approach of data collection.
[email protected]
46

47. 3. Survey
* An alternative to census.
* Sample based study; study/observation through
population representation.
* Mostly used by the researchers.
* A primary method of data collection.
[email protected]
47

48. 4. Focus Group Observation
* A approach of group observation.
* A source for primary data collection.
* Useful in perceptual studies.
* The groups may comprise of 6 to 10 people.
* The issues are discussed by cross questioning
and sharing their views.
* Suitable in case of new product launch and
testing.
[email protected]
48
Can be direct or
indirect, structured
or unstructured

49. 5. Experiments
* A primary method of data collection.
* Can be field or lab experiment based.
* Mostly conducted by using the control groups.
* Most useful in new product testing.
* May be very costly incase of wrong selection of
control groups.
* Sometimes conducted by the help of various
physical tests; eye movements, pupil movements,
skin stimuli etc.
[email protected]
49

50. 6. Interviews
* A popular method of primary data collection.
* Data collected in the basis of personal interaction
with the respondents.
* Can be well-structured or less-structured.
* Useful when small size of observation is enough
for data collection.
* The individuals/subjects are the source of study.
