Research methods can generally be divided into two main categories: Quantitative and Qualitative. This webinar will provide an overview of quantitative methods with a brief distinction between quantitative and qualitative methods. We will focus on when and how to use quantitative research and discuss type of variables and statistical analysis. Presentation will be led by Dr. Carlos Cardillo. About CORE: The Culture of Research and Education (C.O.R.E.) webinar series is spearheaded by Dr. Bernice B. Rumala, CORE Chair & Program Director of the Ph.D. in Health Sciences program in collaboration with leaders and faculty across all academic programs. This innovative and wide-ranging series is designed to provide continuing education, skills-building techniques, and tools for academic and professional development. These sessions will provide a unique chance to build your professional development toolkit through presentations, discussions, and workshops with Trident’s world-class faculty. For further information about CORE or to present, you may contact Dr. Bernice B. Rumala at Bernice.rumala@trident.edu

We
can

research
methods
in
two
main
categories:
Quan>ta>ve

This

provide
an
overview
of
quan>ta>ve

with

between
quan>ta>ve

We
will
focus
on
when
and
how
to

and
discuss
the
role
and
type
of
variables

sta>s>cal

Quan>ta>ve
research
is
‘Explaining
phenomena
by

numerical
data
that
are
analyzed
using
mathema>cally
based
methods
(in
par>cular
sta>s>cs)’.

Quantitative research is ‘Explaining phenomena by collecting numerical data that are analyzed using
mathematically based methods (in particular statistics)’.

It is important to know the type of research methodology you
will use (e.g. for your dissertation).
However, your research idea will dictate the type of research
methodology you use.
This will also emphasize your data collection methods.
If you are collecting numerical data you are most likely
measuring variables and verifying existing theories;
hypotheses and questioning them.

ques1on…
Research
Type
Question
Variables
Descriptive
What
is
this?
Describes
the
current
state
of
variables
Correlational
What
is
happening?
Describes
the
relationship
between
variables.
Quasi-­‐Experimental
What
would
happen
if?
Examines
the
effect
of
a
variable
on
other
variables.
Experimental
How
can
I
make
it
happen?
Examines
the
effect
of
a
variable
that
the
researcher
manipulates
on
other
variables.

§ Your
research

likely
will
determine
the
type

design.
§ The
most
important
part
on
quan>ta>ve
research
is
not
the

§ Both
qualita>ve

research
can
explain
a
phenomenon.
