Document Summary

In the case griggs v. duke power, the supreme court ruled that the test that the company was giving to the employees did not measure the specific job capabilities. The meaning of the test is defined by specific evidence acquired by specific methods. There must be evidence that a test has meaning, and there also has to be evidence that there is validity for the specific situation in which the test is applied. Psychologists always start with the notion that there is no reason to believe a measure is valid. Validity can be defined as the agreement between a test score or measure and the quality it is believed to measure. Validity is the evidence for inferences made about a test score, there are three types of evidence: construct related, criterion related, and content related. Face validity: is the mere appearance that a measure has validity.
