What is
Quantitative
Research?
5
QUANTITATIVE RESEARCH
is “explaining phenomena by
collecting numerical data that are
analyzed using mathematically
based methods (in particular
statistics).”
(Aliaga and Gunderson, 2000)
6
PHENOMENON
is a peculiar incident that can
happen anywhere, with any
discipline or in any organization.
Characteristics
of Quantitative
Research
8
1. It is reliable
and objective.
9
2. It uses
statistics to
generalize a
finding.
10
3. It reduces and
restructures a
complex problem to
a limited number of
variables.
11
4. It looks at the
connections between
variables and establishes
cause and effect
relationships in highly
controlled circumstances.
12
5. It tests
theories or
hypotheses.
13
6. It assumes that
the sample is
representative of
the population.
14
7. The subjectivity
of its methodology
is a secondary
concern.
15
8. It deals with
the details of
the subject.
ADVANTAGES
of Quantitative
Research
17
1. It allows the researcher to
measure and analyze the
data to arrive at an objective
answer to the problem posed
or stated.
18
2. The result is reliable since
the study uses a big sample
of the population.
19
3. Standards are usually used in
choosing the instruments, in
sampling procedures, and in
choosing the most appropriate
statistical treatment, thus making
the research replicable.
20
4. Personal biases can be
avoided since personal
interaction is not part of the
research process.
21
5. Processes involved are
simplified since the steps in
doing quantitative research
are made easy and
systematic.
22
6. Results can be reduced
through statistical
treatments and interpreted
in a few statements.
DISADVANTAGES
of Quantitative
Research
24
1. The context of the study
or the experiment is
ignored in such a way that
it does not consider the
natural setting where the
study is conducted.
25
2. Having a large study
sample requires
researchers to spend more
resources.
26
3. Results are limited since
they are usually based on
the analysis of numbers
and are not obtained from
the detailed narratives.
27
4. It provides less
elaborate accounts of
human perceptions.
28
5. In experimental
research, the level of
control might not be
normally placed in the real
world because it is usually
done in laboratory.
29
6. Preset or fixed
alternative answers may
not necessarily reflect the
true answers of the
participants.
30
7. Findings can be
influenced by the
researcher’s perspective
since most of the time, the
participants are unknown
to him/her.
