What is Utility?
- Utility in the context of testing and assessment refers to the usefulness or practical value of testing to improve efficiency.
- It refers to the practical value of using a test to aid in decision-making.
Factors Affecting a Test's Utility
- Psychometric soundness: a test is said to be psychometrically sound if reliability and validity coefficients are acceptably high.
- Costs: economic, financial, or budget-related factors that must be taken into account in utility analysis.
- Benefits: profits, gains, or advantages of using a test, including economic and non-economic benefits.
Utility Analysis
- A utility analysis is a family of techniques that entail a cost-benefit analysis to yield information relevant to a decision about the usefulness and practical value of a tool of assessment.
- It involves evaluating whether the benefits of using a test outweigh the costs.
Conducting a Utility Analysis
- Expectancy data: an expectancy table provides an indication of the likelihood that a test-taker will score within a certain interval of scores on a criterion measure.
- The Brogden-Cronbach-Gleser formula: a formula used to estimate the dollar amount of a utility gain resulting from the use of a particular selection instrument under specified conditions.
Methods for Setting Cut Scores
- The Angoff Method: a method for setting fixed cut scores that involves expert judgments about how a person with a particular trait or ability would respond to test items.
- The Known Groups Method: a method that involves collecting data on the predictor of interest from groups known to possess and not to possess a trait, attribute, or ability.
- IRT-Based Methods: methods that use item response theory to set cut scores, including the item-mapping method and the bookmark method.
- Other Methods: the method of predictive yield, regression, and discriminant analysis are also used to set cut scores.
