Study Notes
Utility Analysis
- A family of techniques that perform a cost-benefit analysis to determine the usefulness and practical value of an assessment tool.
- Not a single technique but an umbrella term for various methods, each requiring specific data and yielding different outputs.
Naylor-Shine Tables
- Assists in judging the utility of a particular test by determining the increase in average score on some criterion measure through concurrent validation procedures.
Brogden-Cronbach-Gleser (BCG) Formula
- Can be used to estimate utility gains in financial terms.
- Can be modified to estimate utility gains in productivity terms.
Decision Theory and Test Utility
- Cronbach and Gleser (1965) presented a classification of decision problems, various selection strategies, a quantitative analysis of the relationship between test utility, selection ratio, cost of the testing program, and expected value of the outcome, and a recommendation that job requirements be tailored to the applicant’s ability, rather than the other way around.
Expectancy Data & Utility Analysis
- Expectancy tables provide an indication of the likelihood that a test taker will score within some interval of scores on a criterion measure.
- Can provide valuable information for decision-makers.
Taylor-Russell Tables
- Estimate the extent to which inclusion of a particular test in the selection system will improve selection.
- Provide an estimate of the percentage of employees hired by the use of a particular test who will be successful at their jobs, given different combinations of three variables: the test’s validity, the selection ratio used, and the base rate.
Methods for Setting Cut Scores
- The Angoff Method: Experts in the area provide estimates for test takers who have at least minimal competence for the position, indicating how many test items they should answer correctly.
- Known Groups Method: Data is collected for groups known to possess, and not possess, a trait, attribute, or ability of interest. A cut score is then set that best discriminates the two groups’ test performance.
- Item Response Theory (IRT-) Based Methods: In the IRT framework, each item is associated with a particular level of difficulty. A test taker must answer items that are deemed to be above some minimum level of difficulty, which is determined by experts and serves as the cut score.
- Edward L. Thorndike Method: A method of predictive yield.
Cut Scores
- A cut score is a numerical reference point derived as a result of a judgment and used to divide a set of data into two or more classifications, with some action taken or inference made based on these classifications.
- **Relative cut score (reference point or norm-referenced cut score): ** A cut score that is interpreted relative to a group norm.
- Fixed cut score (absolute cut score with reference to minimum level of proficiency): A cut score that is based on a minimum level of proficiency needed for a specific position.
- Multiple cut scores: Used for categorizing test takers based on two or more cut scores, such as in a multistage selection process where each predictor has its own cut score.
