Original Research studies Flashcards
Original research studies provide data in an attempt to…
answer specific research questions
Survey research
can provide useful info regarding trends and practices or evaluate perceptions
Correlational studies
look at relationships between different variables
True experimental study
the only way to draw conclusions regarding causation
Experimental studies can be
either group design or single subject design
Group design involves
random selection of participants and a random assignment to the different experimental groups
Quasi-experimental
when researchers can’t truly randomize the groups
Single subject design
participants are used as their on controls and do not require large sample sizes
Single subject design
Begin with a baseline phase (A) followed by a treatment phase (B)
ABAB design
baseline data collected, then intervention implemented, wait to achieve a stable baseline a second time and then intervention implemented again
Meta-analysis
systemic review plus quantitative syntheses of a group of studies that examined the same variable or variables
Researcher examines
original research studies on a certain topic and results from individual studies are quantified using a common metric so results can be compared.
Narrative reviews
gathers research articles about a topic and summarizes the results
Internal validity
the extent the results of a study can be attributed to differences in the independent variable in the study
Threats to internal validity
History
Maturation
Testing
Instrumentation
Statistical regression
Selection
