validity Flashcards
define validity
whether a measure measures what it claims to be measuring
define internal validity
refers to if the researcher is measuring the effect of the IV on the DV or if there is an effect of extraneous variables
define face validity

based on subjective opinion
define construct validity
if research measures every construct that it should measure
define concurrent validity
where one study of a behaviour gives the same results as another test or study that claims to measure the same behaviour
eg Loftus and Palmer’s first and second studies had a high concurrent validity
define criterion validity
refers to how well a tool can predict future behaviour
define external validity
refers to if the results of the research can be generalised out of the research setting
define population validity
refers to the extent to which the results from the sample can be generalised to the general population
define ecological validity
refers to the extent to which the settings of the study are similar to the natural environment
what are threats to validity?
- order effects
