Quantitative Research
APPROACHES
DESIGNS
EXAMPLES
TYPES
Experimental research12
Depends on a theory (can be verified ir
refuted).
It is used in natural or social sciences.
Research through surveys
Examples.
Telephone surveys
Online surveys
Can be carried out with both single or
multiple groups.
Sample randomly selected
Research through surveys
Used to relate two or more variables
through mathematical anylisis methods.
Example of variables
Relationships
Trens
Patterns
Comparative causal investigaion
Used to draw conclusions about the
case-effect between two or more
variables.
Satisfaction surveys
Many organization contact the users of
their products or sevices after consuming
them, to propose some brief questions
aimed at giving a numerical value to their
satisgaction.
It can be through a telephone call,
automated or not, through an email or
through other methods.
Species characteristics
The work that zoologists do when they find
a new species. They record all the
measurments of the individual foud to
estblish what the average characteristies of
that animal are.
Pharmacological tests
These tests are used to find out if a given
drug migh be effective and to determine
the optimal dose to give.
The tests that are done to test possible
vaccines are one of the examples of
quantitative research.
Two groups are made, one experimental
to which the potential vaccine is applied,
and another control, which only receives
one result.
General staistics
They are scientific methods linked to the
collection, Presentation and analysis of
data, both for drawing conclusions and for
making decisions.
Thanks to those records, other researchers
can benefit from the huge data collection
and analyze it based on the studies they
are doing.
Non-experimental Designs
Experimental Designs
Accrding to different perspectives
Of measurement
Of the information sources from the field
Taken from the analysis Units.
Construction and Validation of
measurements instruments
Pre-experimental
Control groups are used.
Exploratory function.
Pure experimental
The validity of these designs is very high.
Use four aspects related to experimental
designs
Random assigment to group to groups
Control of external factors
Random selection of subjects
Relationship between objectivity and
subjectivity
Setting objectivity conclusions by using
numetical data.
The subject is approached as an object.
The researcher does not interfer as a
partcipant.
Researcher subject/study object
relationship
Approach mode to Study Object
of the units of analysis
Survey studies
It's about asking questions directly to the
subject of study.
Longiudinal
Advantages:
Disadvabtages:
Used to describe changes in the
phenomenon over time.
Cohort studies
Looks for the characteristics of Several
groups of subjects over time.
Cross-sectional
It's about describing the Phenomenon
through the variables, the result are not
high power designs because the
intra-individual difference are minimized
Since the subjects are the same studied in
different moments, thy become the
researchers control
threatened by mortality
Changes of age
Very costly
Quasi-experimental
used when there is no possiblity of
selecting the subjects randonmly.
The conclusions drawn are less valid than a
"Pure" experiment.
Maipulation of external factors
The hypothesis built on a theoretical
body previously sientifically studied,
after that data is collected in order to
be proveed.
