Detailed explanation-1: -Reliability on its own is not enough to ensure validity. Even if a test is reliable, it may not accurately reflect the real situation.
Detailed explanation-2: -A test is valid if it measures what it is supposed to measure. If theresults of the personality test claimed that a very shy person was in factoutgoing, the test would be invalid. Reliability and validity are independent of each other. A measurement maybe valid but not reliable, or reliable but not valid.
Detailed explanation-3: -There is an important relationship between reliability and validity. An assessment that has very low reliability will also have low validity. A measurement with very poor accuracy or consistency is unlikely to be fit for its purpose.
