OBJECTIVE
KNOW THE DIFFERENT RESEARCH DESIGN
SELECT APPROPRIATE RESEARCH DESIGN
RESEARCH DESIGN
logical and coherent overall strategy that
the researcher uses to integrate all the
components of the research study (Barrot,
2017, p 102). In order to find meaning in
the overall process of doing your research
study, a step-by-step process will be
helpful to you.
ACTIVITY 1: PLAN YOUR WORK
Draw a procedural flowchart to illustrate your plan.

RESEARCH DESIGNS: THE BIG FIVE
Descriptive
a design that is exploratory in nature.
The purpose of descriptive research is
basically to answer questions such as
who, what, where, when, and how
much. So this design is best used
when the main objective of the study
is just to observe and report a certain
phenomenon as it is happening.
RESEARCH DESIGNS: THE BIG FIVE
Correlational
The main goal of this design is to
determine if variable increases or
decreases as another variable increases
or decreases. This design seeks to
establish an
association between
variables. It does not seek cause and
effect relationship. It has two major
purposes: (a) to clarify the relationship
between variables and (b) predict the
magnitude of the association
RESEARCH DESIGNS: THE BIG FIVE
Ex-post Facto
. If the objective of the study is
to measure a cause from a preexisting effects, then Ex Post
Facto research design is more
appropriate to use.
RESEARCH DESIGNS: THE BIG FIVE
Quasi
Experimental
This research design aims to
measure the causal relationship
between variables. The effect
measured is considered to have
occurred during the conduct of the
current
study.
Subjects
are
assigned NOT RANDOMLY to
groups (Control or Variable group).
RESEARCH DESIGNS: THE BIG FIVE
Experimental
This research design is based
under a controlled or manipulated
environment. It applies treatment
and manipulation more extensively
compared to quasi-experimental
design. Random assignment of
subjects is done increasing the
validity of the study.
