Quantitative Research
This type of research centers on the objective
measurements and numerical analysis of data collected
through questionnaires or surveys and generalizing the
results across groups of people.

Characteristics of
Quantitative Research
MAIN CHARACTERISTICS OF
QUANTITATIVE RESEARCH
1.It is reliable and objective.
2.It uses statistics to generalize finding.
3.It reduces and restructures complex problem into a
limited number of variables.

4.It looks at the connections between variables and establishes
cause and effect relationships in highly controlled
circumstances.
5.It tests theories or hypotheses.
6.It assumes that the sample is the representative of the
population.

7.The subjectivity of its methodology is a secondary concern.

Quantitative approach involves a greater number of subjects
and enables a broader study, as well as enhancing the
generalization of the results.
Study results are more objective and accurate. Usually, to
support a certain generational by using a summary of data,
quantitative research employs certain procedures on a few
variables to ensure the reliability of data.
Quantitative research, when the right procedure is used, can be
replicated, as well as analyzed in comparison with other similar
works.

STRENGTHS

You can summarize vast sources of information and make
comparisons across categories and over time.
Personal bias can be avoided by keeping a “distance” from
the participating subjects and employing facilitators
unknown to them.

THREE
Quantitative data, while they can test a hypothesis, may be
limited in explaining their context.
The research is often conducted in an artificial setting,
where a certain level fo control is exercised.
Having a large sample requires researchers to spend more
resources.

Results are limited since they are usually based on the analysis
of numbers and are not obtained from detailed narratives.
It provides less elaborate account of human experiences.
Preset of fixed alternative answers may not necessarily reflect
the true answers of the participants.

Descriptive Research
involves the collection of data to either test a hypothesis or describe
variables mentioned in the study. It seeks to describe the current status of
an identified variable. These research projects are designed to provide
systematic information about a phenomenon. The researcher does not
usually begin with a hypothesis but is likely to develop one after collecting
data.

Correlational Research
attempts to determine the level of relation between two or more
quantifiable variables. However, note that the correlation between two
variables does not mean that one variable causes the other, but correlation
predicts the value of one variable based on the other. In this type of design,
relationships between and among a number of facts are sought and
interpreted. This type of research recognizes trends and patterns in data,
but it does not go so far in its analysis to prove causes for these observed
patterns. Because the effect is not the basis of this type of observational
research. The data, relationships, and distributions of variables are studied
only. Variables are not manipulated; they are only identified and are
studied as they occur in a natural setting.

Comparative Research
essentially compare two different groups. These studies may be
experimental or non-experimental. Comparative studies often attempt to
draw conclusions across nationalities or social groups, and they often
include socioeconomic and demographic variables.
