Designing a quantitative study
Quantitative research
Associational
determine a relationship between or within variables
Experimental
researchers manipulate one or more variables
Research materials
all materials need to be pilot tested
Intact classes
used in research for the sake of
convenience or by necessity
have the advantage of
enhancing the face validy of certain types of classroom research
researcher
should consider how the classes are assigned to treatment groups
Counterbalancing
is an experimental design and the tests or tasks
are different for different participants
Correlation
can be used to
test a relationship between or among variables
make predictions
often used in
survey-based research
Design types
truly experimental
that means
with random assigment
quasi-experimental
that means
without random assigment
Comparison group design
participants are randomly
assigned to one group
Control group design
is a control group design
Pre-test design
ensure comparability of the participant
groups prior to their treatment
Post-test design
measure the effects of treatment
Time-series design
involves repeated observations
over a set period of time
One-shot design
used when the study does not have a
pre-test design
post-test design
Meta-analyses
is way of
setting up data for analysis
synthesizing results across studies
