1.What is the difference between reliability and validity?
2.What method of establishing validity is the best?
3.Why is the concept of test utility so important?
4.What is the difference between single-group and differential validity?
5.Why should we use anything other than top-down selection? After all, shouldn’t we
always—hire the applicants with the highest scores?
Solution
1:Reliability refers to consistency or stability whereas validity refers to accuracy of interface or
interpretations
2:Test or Stability, alternate forms of equivalence, internal consistency, content validity
evidence, construct validity evidence.
3: it checks the degree to which a selection device improves the quality of a personnel system,
above and beyond what would have occurred if the instrument not been used.
4:single group predicts for one group, not the other whereas the differential validity is valid for
two but it is more valid for one.
5:because it has the higher quality of selected applicants and relativly objective decision making..
