QUANTITATIVE RESEARCH DESIGNS
TYPES Non-Experimental Experimental
Descriptive Correlational Ex post facto Quasi-experimental Experimental
AIM used to describe a
particular
phenomenon by
observing it as it
occurs in nature
-describe the
person or object of
the study
identifies the
relationship
between
variables.
-direction and
strength of
relationship
used to investigate
a possible
relationship
between previous
events and present
conditions
-means after the
fact, looks at the
possible causes of
an already
occurring
phenomenon
used to establish the cause-
and-effect relationship of
variables
-has lesser validity due to the
absence of random selection
and assignment of subjects.
Here, the independent
variable is identified but not
manipulated. The researcher
does not modify pre-existing
groups of subjects. The group
exposed to treatment
(experimental) is compared to
the group unexposed to
treatment (control)
used to establish the cause-
and-effect relationship of two or
more variables. This design
provides a more conclusive
result because it uses random
assignment of subjects and
experimental manipulations
-
EX “the determination
of the different
kinds of physical
activities and how
often high school
students do it
during the
quarantine period.”
the relationship
between the
amount of
physical activity
done and
student
academic
achievement
“How does the
parent’s academic
achievement affect
the children
obesity?”
the effects of unemployment
on attitude towards following
safety protocol in ECQ
declared areas.
a comparison of the effects of
various blended learning to the
reading comprehension of
elementary pupils.

VARIABLES ACCORDING TO SCALE MEASUREMENT
Examples of ordinal variables include socio
economic status (“low income”,”middle
income”,”highincome”), education level (“high
school”,”BS”,”MS”,”PhD”), income level (“less
than 50K”, “50K-100K”, “over 100K”),
satisfaction rating (“extremely dislike”,
“dislike”, “neutral”, “like”, “extremely like”

KEY CONCEPTS
1.A research design is a strategy for using empirical data to answer
research questions.
2. Two kinds of research designs: nonexperimental and experimental.
3. Descriptive, correlational, ex post facto, quasi-experimental, and
experimental research are the specific types of research.
4. Quantitative research in science and technology is one of the tools and
methods that has led to evolution in many fields, including agriculture,
education, information and technology, medicine, and others. It makes a
significant contribution to problem solving and societal improvement.
5. Variables represents the measurable traits that can change over the
course of a scientific experiment.
6. Variables are classified based on their values, measurement scale,
and relationship.
