1. MODULE 02 –
QUANTITATIVE
RESEARCH DESIGN

2. At the end of this module, you
should be able to:
Cognitive
• Define quantitative research accurately
• Identify the different characteristics of quantitative research
• Create graphic organizer showing the different classifications of
quantitative research
• Cite uses of quantitative research
Affective:
• Show the importance of quantitative research in Covid 19 contact tracing
Psychomotor:
• Make and use different research tools under quantitative research design

3. DIRECTION: Carefully analyze the picture
presented and answer the questions that follow

4. QUESTIONS
1. What do you know about Covid 19 Contact
tracing?
2. How does Covid 19 contact tracing is being
done?
3. Do you think it is effective? Why or Why not?

5. Quantitative Research
• Quantitative research is an
inquiry into a social or human
problem based of testing
theory composed of
variables, measured with
numbers and analyzed with
statistical procedures in
order to determine whether
the predictive generalizations
of the theory hold true.

6. ● Quantitative research makes you focus
your mind on specific things by means
of statistics that involve collection and
study of numerical data.
● Thus, to give the basic meaning of
quantitative research is to say that
research is a way of making any
phenomenon or any sensory experience
clearer or more meaningful by gathering
and examining facts and information
about such a person, thing, place, or
event appealing to your senses.
Quantitative Research

7. ● Involving measurements and
amounts, quantitative research
seeks to find answers to
questions starting with how many,
how much, how long, to what
extent, and the like.
● Answers to these questions come
in numerals, percentages, and
fractions, among others.
Quantitative Research

8. EXAMPLE OF QUANTITATIVE
RESEARCH
1. Weight
2. Height
3. Age of person
4. Annual Income of an
employee
5. The general weighted average
Quantitative Research

9. You work in an office that has a water cooler. The water cooler holds
twenty gallons of water. Your boss asks you to figure out how many refills
your office will need every month, because she’s trying to do the budget
What method you would use? (Qualitative and/or quantitative) Why?

10. Characteristics of
Quantitative Research

11. Characteristics of Quantitative
Research
1. OBJECTIVE. Quantitative
research seeks accurate
measurement and analysis of
target concepts. It is not based
on mere intuition and guesses.
Data are gathered before
proposing a conclusion or
solution to a problem.

12. Characteristics of Quantitative
Research
2. CLEARLY DEFINED
RESEARCH QUESTIONS. The
researchers know in advance
what they are looking for. The
research questions are well-
defined for which objective
answers are sought. All aspects
of the study are carefully
designed before data are
gathered.

13. 3. STRUCTURED RESEARCH
INSTRUMENTS. Standardized
instruments guide data collection,
thus, ensuring the accuracy,
reliability and validity of data. Data
are normally gathered using
structured research tools such as
questionnaires to collect measurable
characteristics of the population like
age, socio-economic status, number
of children, among others.
Characteristics of Quantitative
Research

14. 4. NUMERICAL DATA.
Figures, tables or graphs
showcase summarized data
collection in order to show
trends, relationships or
differences among variables. In
sum, the charts and tables
allow you to see the evidence
collected.
Characteristics of Quantitative
Research

15. 5. LARGE SAMPLE SIZES. To
arrive at a more reliable data
analysis, a normal population
distribution curve is preferred.
This requires a large sample size,
depending on how the
characteristics of the population
vary. Random sampling is
recommended in determining the
sample size to avoid researcher’s
bias in interpreting the results.

Research

Research

16. 6. REPLICATION. Quantitative
methods can be repeated to
verify findings in another
setting, thus strengthen and
reinforcing validity of findings
eliminating the possibility of
spurious conclusions.
Characteristics of Quantitative
Research

17. 7. FUTURE OUTCOMES. By
using complex mathematical
calculations and with the aid of
computers, if-then scenarios
may be formulated thus
predicting future.
Characteristics of Quantitative
Research

18. Strengths and
Weaknesses of
Quantitative Research

19. Strengths and Weaknesses of
Quantitative Research
Strengths Weaknesses
1. It is objective. The most reliable and
valid way of concluding results, giving way
to a new hypothesis or to disproving it.
Because of bigger number of the sample of
a population, the results or generalizations
are more reliable and valid. Since it
provides numerical data, it can’t be easily
misinterpreted.
1. Quantitative research requires a large
number of respondents. It is assumed that
the larger the sample is, the more
statistically accurate the findings are
2. The use of statistical techniques
facilitates sophisticated analyses and
allows you to comprehend a huge
number of vital characteristics of data.
2. It is costly. Since, there are more
respondents compared to qualitative
research, the expenses will be greater in
reaching out to these people and in
reproducing questionnaires.

20. Strengths and Weaknesses of
Quantitative Research
Strengths Weaknesses
3. It is real and unbiased. If the
research is properly designed it filters out
external factors, and so can be seen as
real and unbiased.
3. The information is contextual factors
to help interpret the results or to explain
variations are usually ignored. It does not
consider the distinct capacity of the
respondents to share and elaborate
further information unlike the qualitative
research.
4. The numerical data can be analyzed
in a quick and easy way. By employing
statistically valid random models,
findings can be generalized to the
population about which information is
necessary.
4. Much information are difficult to gather
using structured research instruments,
specifically on sensitive issues like pre-
marital sex, domestic violence, among
others

21. Strengths and Weaknesses of
Quantitative Research
Strengths Weaknesses
5. Quantitative studies are replicable.
Standardized approaches allow the study to
be replicated in different areas or over time
with formulation of comparable findings.
5. If not done seriously and correctly, data
from questionnaires may be incomplete
and inaccurate. Researchers must be on
the look-out on respondents who are just
guessing in answering the instrument.
6. Quantitative experiments are useful for
testing the results gained by a series of
qualitative experiments, leading to a final
answer, and narrowing down of possible
directions to follow

22. DIRECTION: Write A if it’s an advantage when using
quantitative research and N if it’s not.
__________1. It is a great way to prove or disprove hypothesis.
__________2. It can be difficult and expensive depending on the
topic
__________3. It must be carefully planned
__________4. Results are often unreal and biased
__________5. It requires less time and effort.

23. SYNTHESIS
●The data is usually gathered using structured
research instruments.
●The results are based on larger sample size
that are the representative of the population.
●The research study can usually be replicated
or repeated given its high reliability
●Researchers has a clearly defined research
question to which objective answers are
sought

24. SYNTHESIS
● All aspect of the study is carefully designed before
the data is collected.
● Data are usually in the forms of numbers and
statistics, often arranged in tables, charts, figures or
other non-textual forms
● Project can be used to generalized concepts
more widely, predict future results or investigate
causal relationships
● Researcher uses tools, such as questionnaires or
computer software to collect numerical data.
