Answer 1

• 4.Reliability refers to the dependability or consistency or stability of the test scores. It does not go beyond it.Validity is concerned with the extent to which the purpose of the test is being served. It studies how truthfully the test measures what it purports to measure.
• If data are valid, they must be reliable. If people receive very different scores on a test every time they take it, the test is not likely to predict anything. However, if a test is reliable, that does not mean that it is valid. For example, we can measure strength of grip very reliably, but that does not make it a valid measure of intelligence or even of mechanical ability. Reliability is a necessary, but not sufficient, condition for validity.
  
• A valid test is always reliable. If a test truthfully measures what it purports to measure is both valid and reliable.
