Answer to Question 1

Answer: Summary of suggested answer -
 Reliability refers to the consistency of measurement, usually across time, but also across judges. It is a measure of how much error there may be in a test. One example is the job interview- different interviewers may judge the same candidate differently, etc.
 Validity is the extent to which scores on a test accurately determine the test-taker's abilities and performance.

A test that is not valid does not test what it is supposed to test, or does not do it accurately. A test may be reliable and yet not be valid, but a test that is not reliable is not valid. To decrease the chances of lawsuits claiming discrimination, firms should ensure that selection techniques are job related. In other words, the best defense is evidence of the validity of the selection process. For example, if a minority group member turned down for a job claims discrimination, the organization should have ample evidence to document the job relatedness of its selection process. This evidence should include job analysis information and evidence that test scores are valid predictors of performance.

Answer to Question 2

True
