A common method used for demonstrating Criterion-Related Validation.
- Two identifying features of the predicitive validity techniqure are (1) use of job applicants as participants in the study and (2) a time interval between testing and collecting criterion data.
-The test is administered to these applicants, and then their responses are filed away, unscored, for a later time.
Ex. Those who are applying for the job is the sample for the study.
You either predict future performance, or you correlate performance on two tests separated by a decent time interval (SAT vs. GPA on report cards a year later.) If you see "expect", you are probably dealing with predictive validity.
