1 Staffing & Strategy Effectively done, staffing has an impact on the bottom line (ineffectively done, also impacts) Financial investment in people should pay off Litigation avoidance Achievement of organizational goals

2 Reliability Defined The degree to which the technique produces consistent results

3 Sources of Error in Reliability Estimates Person taking test Person giving the test Person scoring test Test taking conditions

4 Ways to Estimate Reliability Test-re-test Parallel or equivalent forms Internal consistency

5 The Correlation Coefficient A statistical technique that measure the extent to which scores from two variables are related to each other. It ranges from - 1.0 to +1.0. A positive correlation: As scores on one variable go up so do scores on the other one. Ex. Height and Weight A negative correlation: As scores on one variable go up scores on the other one go down. Ex. Age and Speed

6 Defining Validity Validity: Extent to which a test is actually measuring what it claims to measure

7 Types of Validity Criterion-related Concurrent Criterion-related Predictive Content Construct

8 Types of Applicant Information Abilities, skills, knowledge Personality, interests preferences Other characteristics

9 Overview of Selection Tools Abilities, skills, knowledge –Cognitive tests, Psychomotor tests, Work simulations Personality, interests, preferences –Personality tests, Interest & preference inventories, Handwriting analysis, Polygraph tests Other characteristics –Drug screening, fitness to work, reference checks, application blanks

11 Reference Checks To verify information given by job applicants To serve as a predictor for future job success To uncover background information

12 COGNITIVE ABILITY General intelligence -- ability to think analytically, reason, problem solve Verbal Numerical General knowledge Reasoning ability Spatial ability

13 Special Ability Tests Mechanical Ability Clerical Ability Physical Ability Motor skills: manual dexterity, eye- hand coordination, reaction time Fitness: strength, stamina

14 Backwards & Forwards Summing up: Today we examined reliability and validity of selection techniques. Various ways of estimating reliability and validity were discussed.
