criterion-related validity

Criterion-related validity refers to how well a test measuring general knowledge predicts performance in related areas or real-world outcomes. For instance, if a general knowledge quiz accurately forecasts how someone performs on a more comprehensive exam or in a job requiring knowledge, the quiz has strong criterion-related validity. Essentially, it shows that the test reflects what it aims to assess and can be correlated with other established measures of knowledge. This type of validity ensures that the results are meaningful and useful in practical situations.
