One difference between reliability and validity is that reliability
 
  a) can be summarized by a single number, while validity is usually evaluated on a continuum.
   b) is defined in terms of a particular set of examinees, while validity is independent of any group of examinees.
   c) can only be established over a period of time, while validity can be established fairly quickly in the test development process.
   d) includes considerations of how a test is used, while validity is an internal quality of a test.
