The document is an overview of quantitative research methodology presented by Dr. Carlos Cardillo, focusing on defining and differentiating quantitative and qualitative research methods. It emphasizes the importance of choosing the right research design based on research questions and variables, outlining various types of quantitative research designs such as descriptive, correlational, quasi-experimental, and experimental. The presentation also highlights the relevance of statistical analysis in quantitative research while contrasting it with qualitative methods.

We
can
classify
research
methods
in
two
main
categories:
Quan>ta>ve
and
Qualita>ve
This
webinar
will
provide
an
overview
of
quan>ta>ve
methods
with
a
brief
dis>nc>on
between
quan>ta>ve
and
qualita>ve
methods.
We
will
focus
on
when
and
how
to
use
quan>ta>ve
research
and
discuss
the
role
and
type
of
variables
and
sta>s>cal
analysis.

Quan>ta>ve
research
is
‘Explaining
phenomena
by
collec>ng
numerical
data
that
are
analyzed
using
mathema>cally
based
methods
(in
par>cular
sta>s>cs)’.

and

Quantitative research is ‘Explaining phenomena by collecting numerical data that are analyzed using
mathematically based methods (in particular statistics)’.
Aliaga and Gunderson (2000)

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.

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.
