Reliability is necessary for validity but not sufficient.why?
Answered by admin @
If test scores are not reliable, they cannot be valid since they will not provide a good estimate of the ability or trait that the test intends to measure. Reliability is therefore a necessary but not sufficient condition for validity. Reliability refers to the accuracy or repeatability of the test scores.
