Validity Flashcards
Define internal validity
The extent to which the results of the study are due to the tested variable
Define external validity
The extent to which the results of the study can be generalised to other people, settings and across time
Define face validity
Does the test seem to be measuring what it is supposed to measure
Define concurrent validity
The results correlate with already validated measures
Define predictive validity
How well the study predicts future behaviour
Define temporal validity
Results are valid if they remain the same over time after retesting
How would you increase internal validity?
Controlling extraneous variables and ensuring reliability
How would you increase external validity?
Developing realistic tests and using natural settings
What is validity?
The extent to which results accurately measure what they are supposed to measure
Define ecological validity
The extent to which a study can be generalised to other settings
Define population validity
The extent to which a study can be generalised to other groups/people
What is the best way to test validity?
Concurrent validity checks - checking the results against other established measures/results
Name a study that has high ecological validity
