LESSON 7 Flashcards
known as the ‘‘criterion-related validity’’
pragmatic measures
this ‘‘test the practical value of a particular research instrument’’ or tool and focus on the questions ‘‘does it work’’
pragmatic measures
refers to an ‘‘instrument’s ability to distinguish individuals who differ on a present or current criterion’’
concurrent validity
adequacy of an instrument in ‘‘differentiating between people’s performance on some future criterion”
predictive validity
attempts to answer the question “what is the instrument really measuring?”
construct validity
it is used mainly for measures of traits or feelings, such as generosity, grief, or satisfaction
construct vaalidity
this is carried out by comparing two groups
contrasted groups
it is designed to test the theory or conceptual framework underlying the instrument
experimental manipulation
MTMM meaning
multi-trait multi-method matrix method
the ‘‘premise that different measures of the same construct’’ should produce very similar results, that measures of different constructs
MTMM
the evidence that different methods of measuring a ‘construct yield similar results’
convergent validity
the ability to ‘differentiate construct from other similar constructs’
discriminant validity
the ‘preferred method of establishing construct validity’ whenever it is possible to use it
