Define reliability and validity. Can a test have high reliability and low validity or vice versa?

What will be an ideal response?

Reliability refers to the consistency of a test or how likely it is that a person will get the same score twice. Psychologists measure reliability by a correlation between scores taken at different times, or scores on different parts of a test. Validity refers to whether a test measures what it is supposed to measure. One way to measure validity is to find the correlation between scores on a test and some activity outside the test. A test can have high reliability without being valid, if it provides consistent scores on questions that don't test what the test is supposed to test. However, a test that is not reliable cannot be valid, because if the scores vary haphazardly, they cannot predict performance.
