Chapter 7: Utility Flashcards
We may define _____ in the context of testing and assessment as the usefulness or practical value of testing to improve efficiency.
In the language of psychometrics, _____ (also referred to as test _____) means much the same thing; it refers to how useful a test is. More specifically, it refers to the practical value of using a test to aid in decision-making
utility
Factors That Affect a Test’s Utility (3)
1) Psychometric soundness
2) Costs
3) Benefits
Factors That Affect a Test’s Utility:
A test is said to be _____ for a particular purpose if reliability and validity coefficients are acceptably high.
An index of reliability can tell us something about how consistently a test measures what it measures; and an index of validity can tell us something about whether a test measures what it purports to measure; but an index of utility can tell us something about the practical value of the information derived.
psychometrically sound
Factors That Affect a Test’s Utility
Generally speaking, the higher the _____ of test scores for making a particular decision, the higher the utility of the test is likely to be.
criterion-related validity
Would it be accurate to conclude that “a valid test is a useful test”?
no; it is not the case that “a valid test is a useful test”.
Factors That Affect a Test’s Utility
In fact, one of the most basic elements in any utility analysis is the financial cost of the selection device (or training program or clinical intervention) under study
Cost
Factors That Affect a Test’s Utility
_____ refers to profits, gains, or advantages. As we did in discussing costs associated with testing (and not testing), we can view benefits in both economic and noneconomic terms.
In industrial settings, a partial list of such noneconomic benefits—many carrying with them economic benefits as well—would include increase in quality of workers’ performance, increase in quantity of workers’ performance, decreases in time to train workers’ reduction in number of accidents, reduction in worker turnover.
Benefits
A _____ may be broadly defined as a 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.
In a most general sense, a _____ may be undertaken for the purpose of evaluating whether the benefits of using a test (or training program or intervention) outweigh the costs.

How Is a Utility Analysis Conducted? (2)
An _____ can provide an indication of the likelihood that a testtaker will score within some interval of scores on a criterion measure—an interval that may be categorized as “passing”, “acceptable”, or “failing”
expectancy table
The _____ tables are formulated in terms of differences in average criterion score between the selected group and the original group; Taylor and Russell use differences in the percent successful between the selected group and the original group.
Naylor-Shine
How Is a Utility Analysis Conducted? (2)
The independent work of Hubert E. Brogden and a team of decision theorists Cronbach and Gleser, has been immortalized in a formula for the dollar amount of a utility gain resulting from the use of a particular selection instrument under specified conditions.
In general, utility gain refers to an estimate of the benefit (monetary or otherwise) of using a particular test or selection method.
By the way, a modification of the _____ formula exists for researchers who prefer their findings in terms of productivity gains rather than financial ones. Here, productivity gain refers to an estimated increase in work output.

Some Practical Considerations: (3)
1) The pool of job applicants
2) The complexity of the job
3) The cut score in use
Some Practical Considerations: (3)
Closely related to issues concerning the available pool of job applicants is the issue of how many people would actually accept the employment position offered to them even if they were found to be a qualified candidate
The pool of job applicants
Some Practical Considerations: (3)
The more _____, the more people differ on how well or poorly they do that job. Whether or not the same utility models apply to jobs of varied complexity, and whether or not the same utility analysis methods are equally applicable, remain matters of debate.
