- Refers to the usefulness or practical value of testing to improve efficiency.
- Factors that Affect a Test's Utility:
- A family of technique that entail a cost benefit analysis designed to yield information relevant to a division about the usefulness and/or practical value of a tool assessment.
- How Is a Utility Analysis Conducted?
- Estimate of the benefit of using a particular test or selection method.
- Estimated increase in work output.
- Some Practical Considerations When Conducting Utility Analyses
- A reference point derived as a result of judgment and used to divide a set of data into two or more classifications.
- A reference point that is set based on norm-related considerations rather than on the relationship of test scores to a criterion.
- Cut score is set with reference to the performance of a group (or some target segment of a group.)
- Cut score that is typically set with reference to judgment concerning a minimum level of proficiency required to be included in a particular classification.
- Refers to the use of two or more cut scores with reference to one predictor for the purpose of categorizing test takers.
- A cut score in place for each predictor used.
- Assumption is made that high scores on one attribute can compensate for low scores on another attribute.
- Method for Setting Cut Scores:
- In this method judgments of experts are averaged.
- Collection of data on the predictor of interest from group known to possess and not to possess trait, attribute, or ability.
- This is based on test taker's performance across all items on a test.
- Test items are listed, one per page, in ascending level of difficulty.
- Family of statistical techniques used to shed light on the relationship between certain variables and two or more naturally occurring groups.
