4.2.3.1 TYPES OF VALIDITY Flashcards
what does validity do?
- focuses on accuracy
- accurately measuring what the study sets out to
- looks at what extent the findings can be generalised to the wider population and out of the research setting
what is internal validity?
how can it be improved?
- measures whether the results are due to their manipulation of the IV and not confounding variables
- can be improved by reducing investigator effects and demand characteristics
what is external validity?
- measures whether the results can be generalised beyond the research setting
looking at:
-> ecological validity
-> population validity
-> temporal validity
- can be improved by setting research/experiments in naturalistic environments
what is ecological validity?
whether it can be generalised to other settings
what is population validity?
whether it can be generalised to other people
what is temporal validity?
when it can be generalised over time
- assesses how valid it remains over time
what is predictive validity?
assesses validity by predicting how well a test does at predicting future behaviour
what is concurrent validity?
assesses through correlation, correlating scores from research already existing and known to be valid
what is face validity?
assesses whether something is what it looks like, to what extent does the item look like what the test measures
