Utility
Cards in this deck (6)
- 1What three methods would you use to establish usefulness of a selection device?1) Taylor-Russell tables: estimate % of total hires who will be successful employees
2) Lawshe tables: Probablity of success for each applicant based on test scores
3) Utility formula: provides estimate of £ organisation will save. - 2What three pieces of information are needed for Taylor-Russell Tables?1) Test's criterion validity coefficient
- obtained by validation study -> high validity=more successful
2) Selection ration
- % applicants organisation must hire
- # openings / # applicants -> Lower selection ratio = more useful
3) Base rate of current performance
- % of current employees considered successful - 3What three pieces of information are needed for Lawshe tables?Lawshe - provides probability that particular applicant will be successful.
1) Test's criterion validity coeffiecient
2) Base rate of current performance
- % of current employees considered successful
3) Applicants test score percentile rank
- divided in 20%'s - 4What two pieces of information are needed for Utility formula?- DEtermines how much £ the organisation will save by using new selection device.
- 5 things needed:
1) # of employees hired per year (n)
2) average years of tenure (t)
3) test validity (r)
4) SD of performance in £
5) Mean standardized predictor score of selected applicants (m) - 5What is crucial for maximum utility?Validity -> high as possible
Current Success Rate -> low as possible
Selectivity -> higher the better - 6What conditions are there when testing is less useful?- Lower level recruitment where job/training success are not critical
- Most people can prove successful
- A very small number of applicants
- Individual differences in job performance are small
- Failures can be tolerated
