Is that even internally valid?
Do I trust your study?
Validity on the outside.
Experiment this!
Quasiiiiiiiiiiiiiiii Chop
100
This threat is related to the inability to determine which variable caused another - chicken or egg problem.
What is ambiguous temporal precedence?
100
A variable that may compete with the independent variable.
What is an extraneous variable?
100
The ability to generalize to those not in the study.
What is population validity?
100
The best method to control for confounding/extraneous variables in experimental research.
What is random assignment?
100
The one thing that makes a study quasi or true experimental.
What is random assignment?
200
This threat is a result of taking a test multiple times and getting "better" at taking a test.
What is testing effect?
200
A type of validity focused on the causation of variables.
What is internal validity?
200
The extent to which results can generalize over time.
What is temporal validity?
200
The weakest experimental design.
What is one-group posttest only design?
200
A quasi - experimental method where a baseline is achieved, a treatment is given, and a post baseline is then established - over time.
What is Interrupted Time-Series Design?
300
This threat is controlled by having a control/comparison group. It refers to things that can happen during a treatment.
What is the history effect?
300
The extent to which findings can be generalized out.
What is external validity?
300
The extent to which results can extend to different settings.
What is ecological validity?
300
An experimental design that simultaneously investigates multiple variables including interaction effects.
What is factorial design?
300
A method where a treatment and control group regression line is developed and then compared for treatment effect.
What is a regression-discontinuity design?
400
A set of threats that occurs when threats work together during a study.
What is additive and interactive effects?
400
Validity associated with operationalizing variables as to be consistent with previous theory/measurement.
What is construct validity?
400
The degree to which findings can extend to other variations of the treatment.
What is treatment variation validity?
400
A design where all students receive all of the treatments - at different times.
What is repeated-measures design?
400
When a researcher uses a single person over time to test the effect of a treatment.
What is a single-case design?
500
A threat related to the idea that low scores usually increase and high scores usually decrease.
What is regression artifacts?
500
Validity focusing on statistical STRENGTH in making conclusions.
What is statistical conclusion validity?
500
The ability to extend results to similar dependent variables.
What is outcome validity?
500
Random assignment + treatment + observation for a treatment and control group.
What is a posttest-only control-group design?
500
One of the ways to assessment treatment effects of single-case designs.
What is visual inspection or statistical analysis?
