Educational Psychology / Unit 12 EDP 1104 short lesson, about 20 seconds
Validity: Interpretations and Uses
Captions available
The idea
Validity is the adequacy of the interpretations and uses made of test results for a group, not a property of the test itself, and it is a matter of degree.
In practice
A reading test may support placing students in reading groups but not grading their science.
Where people slip
Ask "valid for what?" rather than "is this test valid?"
