Module 4: Utility Flashcards
Utility
usefulness or practical value of testing to improve efficiency
What can utility identify?
can tell us something about the practical value of the information derived from scores on the test
What can utility help with?
Helps us make better decisions
What makes higher utility?
Higher criterion-related validity = higher utility
What is one of the most basic elements in utility analysis?
One of the most basic elements in utility analysis is financial cost of the selection device
Cost
disadvantages, losses, or expenses both economic and noneconomic terms
Benefit
profits, gains or advantages
When does the cost of test administration become worth it?
The cost of test administration can be well worth it if the results is certain noneconomic benefits
Utility Analysis
family of techniques that entail a cost-benefit analysis designed to yield information relevant to a decision about the usefulness and/or practical value of a tool of assessment
Expectancy table
provide an indication that a testtaker will score within some interval of scores on
a criterion measure – passing, acceptable, failing
What might utility predict?
Might indicate future behaviors, then if successful, the test is working as it should
Taylor-Russel Tables
provide an estimate of the extent to which inclusion of a particular test in the selection system will improve selection
Selection Ratio
numerical value that reflects the relationship between the number of people to be hired and the number of people available to be hired
Selection Ratio Formula
number of hired candidates / total number of candidates
Base Rate
percentage of people hired under the existing system for a particular position
What is one limitation of Taylor-Russel Tables?
One limitation of Taylor-Russel Tables is that the relationship between the predictor (test) and criterion must be linear
Naylor-Shine Tables
entails obtaining the difference between the means of the selected and unselected groups to derive an index of what the test
is adding to already established procedures
Brogden-Cronbach-Gleser Formula
used to calculate the dollar amount of a utility gain resulting from the use of a particular selection instrument
Utility Gain
estimate of the benefit of using a particular test
Productivity Gains
an estimated increase in work output
What does it mean when a job is more complex?
The more complex the job, the more people differ on how well or poorly they do that job
Cut Score
reference point derived as a result of a
judgement and used to divide a set of data into two or more classifications
Types of Cut Scores
- Relative Cut Score
- Fixed Cut Scores
- Multiple Cut Scores
- Multiple Hurdle
- Compensatory Model of Selection
Relative Cut Score
reference point based on norm-related considerations (norm-referenced), not fixed per se
