Types of Validity & Reliability Flashcards
FACE VALIDITY
Does something look like it will measure what it is supposed to measure? For example is an IQ test really measuring how intelligent somebody is?
CONSTRUCT VALIDITY
Do the measures relate to the assumed characteristics of what is being assessed? For example a driving test measures hazard perception and different aspects of driving skill, or a tape measure measuring the length of something.
CONCURRENT VALIDITY
How closely two different tests of the same behaviour/skill agree with eachother
CRITERION VALIDITY
the extent to which a measure can predict the performance or behaviour of the measured thing. For example the extent to which GCSE results accurately predicts A Level results.
EXTERNAL VALIDITY
Looks at factors outside of the study such as who the study aimed to be representative of and where we can generalise the findings of behaviour too
((To the extent that the results can be generalised))
ECOLOGICAL VALIDITY
How true to life the study is
If it does then the study is high in ecological validity and therefore mundane realism. If it doesn’t, then the study is low in ecological validity and the results of behaviour cannot be generalised to what would occur in real life
POPULATION VALIDITY
To the extent to which the sample can be generalised to similar and wider population
Unfortunately if a study suffers from low population validity it also means there is trouble in generalising the study results of other individuals. Thus limiting how useful the research is.
INTERNAL RELIABLITLITY
whether the procedure of a study is standardised (controlled) so that each participant experiences the same thing
EXTERNAL RELIABILITY
This is the extent to which the results of a procedure can be replicated from one time to another.
If a study has external reliability it means the measures used to measure behaviour should produce consistent results if repeated again and again
INTER-RATER RELIABILITY
If there is high inter-rater reliability this essentially means that two or more individuals have a high agreement on a score and therefore the measurement of behaviour is reliable.
INTERNAL RELIABILITY
whether the procedure of a study is standardised (controlled) so that each participant experiences the same thing
