The document provides an overview of quantitative research methods, clarifying the nature and purpose of scientific research, the research process, and the characteristics distinguishing it from other knowledge acquisition methods. It explores different research techniques, including surveys and experiments, while discussing concepts such as validity and reliability in measurement. Additionally, the document emphasizes the significance of theory, conceptualization, and operationalization in conducting research.

2. 1.What is scientific research? What is
quantitative research?
• Methods of knowing:
▫ by tenacity (“something is true
because it has always been true”);
▫ by intuition (“something is true
because it’s self-evident and stands to
reason”);
▫ by authority (“something is true
because a trusted source says so”);
▫ by scientific research (“something is
true because research results tell so”).

3. 1.What is scientific research? What is
quantitative research?
• Characteristics of Scientific Research (Wimmer
& Dominick, 1997, pp. 9-11):
▫ public (vs. private)
▫ objective (vs. subjective)
▫ empirical (vs. speculative)
▫ systematic and cumulative (vs. ad-hoc and
discontinued)
▫ predictive (vs. time/space-bound)

4. 2.Why do we the scientific research?
• Purposes of Scientific Research: to
discover/generate general laws underlying a
social process (i.e., theory) that help to
▫ describe the current state or past trend of the
process
▫ explain the causes of the process
▫ predict the future trajectory of the process
▫ control (i.e., intervene) the direction, pace, and
outcome of the process

5. A research for this class…
• Pre-course survey
• Q: what decisions can I make from the this data?

6. 3.Who is conducting the research?
• Decision makers in industry and academic
initiated the research
• In industry:
▫ Internally: a research expert within the
organization
▫ Externally: a research company
 Arab Media Outlook was conducted by Deloitte
 Nielson: market research company “what people
watch, what people buy”
• In academic: a professor

4.1 Pre-research
4.2 Research
4.3 Post-research

10. 4.1. Pre-research Phase
• Identifying a need for research
• Research questions guide the research
• Research hypotheses
• Deciding on the appropriate Research Methods

11. Research Methods
• Quantitative or Qualitative?
▫ Survey
▫ Content analysis
▫ Experiment
▫ Interview
▫ Focus group
▫ Observation
▫ Case study
▫ ……

12. Basic Types of Qualitative Methods

13. Basic Types of Quantitative Methods
Survey Experiment Content analysis

14. What is Survey?
• Survey is a research technique that uses a
standardized questionnaire to collect
information about attitudes, opinions,
behaviors, and background and lifestyle
characteristics from a sample of respondents.

15. What Is Experiment?
Experiment is a procedure in which subjects are
first randomly assigned to experimental and
control conditions, with those under
experimental condition(s) given exposure to
certain stimulus or treatment whereas those
under control condition given no exposure, in
order to assess the effects of the message.

19. What is Content Analysis?
• Content analysis is a research method for the
studying and analyzing communication content
in a systematic, objective, and quantitative
manner for the purpose of measuring variables.
• In content analysis, communication content is
examined independently of those who produced
it. Communication professionals are not queried
about their attituds, opinions, and motivations
in the production of the content.

20. Example
• A research on News Produsers:
• Factors Influencing User Engagement in
Instagram News Produsers’ Accounts: A Case
in the UAE (Mansour Alameri & Shujun Jiang,
2018)

24. 4.2. Research Phase
• In industry:
▫ Research expert meets executives to learn
research question, research methods, relevant
population, timetable, budget
▫ Then, literature review—measurement—train data
collectors—collect data– data analysis—report
• In academic
▫ Professors do all the above and write a paper for
conference or academic journal publication

25. 4.3. Post-research phase
• Executives evaluate the research results and
make decision
• Professors evaluate the results and limitations to
improve future studies.

26. 5.What is the language of research?
• 5.1. Theory
▫ “Theory is a set of related propositions that presents a
systematic view of phenomena by specifying
relationships among concepts.” (Winner and
Dominick, 1997, p. 11)
▫ Theory aims to explain the causes and predict the
consequences of a process as general as possible (i.e.,
as time-less and space-less as possible).

27. 5.2 What Is Concept?
• A concept is the smallest element in a theory, as
bricks in a building;
• A concept is the abstract representation of a
phenomenon under investigation;
• Some authors call a broad concept as “construct”
that entails a number of narrow concepts; however,
the difference between construct and concept is
always relative because a construct may be the
constituent concept of another construct whereas a
concept may contain other concepts.

28. 5.3 What Is Relationship?
• A relationship is a specification of the structural
connection between or among concepts in a
theory;
• The specification of a relationship includes:
▫ the nature (correlational or causal) of the relationship;
▫ the form (linear or otherwise) of the relationship;
▫ the direction (positive or negative) of the relationship;
▫ the strength (strong or modest) of the relationship.

29. Examples of Relationship
• Need for the Internet: dissatisfaction with the
conventional media and expected satisfaction with the
Internet drives adoption and use of the Internet

30. 5.4 What Is Proposition?
• A formal presentation of the nature, form,
direction, and strength of a relationship
between/among theoretical concepts, which
could and should be in all three formats:
▫ Verbal description
▫ Graphic illustration
▫ Mathematical specification

31. Example of a Proposition
• Knowledge gap increases over time as the
different segments of a society learn new
information at a differential rate.

Conceptualization Fieldwork Analysis

35. 5.7 What Is Conceptualization?
• A thought process to identify key concepts and
formulate their structural relationship, based on
existing theory and past research;
• Conceptualization is to translate concrete events
and/or phenomena to abstract symbols and
propositions, which will necessarily ignore rich
details of the reality.

37. 5.8 What Is Operationalization?
• A process to translate the abstract concepts into
concrete variables that can be quantitatively
measured by a questionnaire (in survey), coding
sheet (in content analysis), physiological
instruments (in experiment), and other means of
data collection;
• The quality of operationalization is evaluated by
▫ validity
▫ reliability
▫ practicality

40. 5.9 What is Measurement?
• Measurement: is a set of rules for assigning
numbers, which represent values of varying
degrees of precision, for reported or observed
behaviors, attitudes, opinions, and other
individual, group, organization, content, or issue
characteristics.
• Measurement should be
 Valid
 Reliable

41. 5.9.1 What is Validity and Reliability?
• Validity addresses whether or not you have
asked the right question to get the answers that
represents the phenomenon you are
researching.
• Reliability addresses the issue of the consistency
of the question that measures the concept being
studied.

42. 5.9.1 What Is Validity & Reliability?
• Validity: the extent to which the results of a
study (i.e., the concepts and/or their
relationship) represent what the study is
intended to find.
• Reliability: the extent to which the results of a
study can be replicated among the same
population at a different time or among different
population(s) at any time.

43. 5.9.1 What is Validity & Reliability?
• Internal validity is concerned with whether the
measurement is an accurate representation of
the concept being studied.
 E.g. internet use vs internet access
• External validity refers to whether the results of
a research study are generalizable to the
population of interest.
 E.g. A study of college student vs population

44. 5.9.1 Validity vs. Reliability
Invalid & Unreliable Reliable but Invalid Valid & Reliable

45. 5.9.1 Evaluation of Validity and
Reliability
• Validity is a conceptual question that doesn’t
have any direct and conclusive way of testing.
• Reliability is an empirical question that can be
evaluated based on test-retest data.
