Study Notes

Utility

Psychometrics defines utility (also called test utility) as the practical value of using a test in decision-making.
It helps determine if a test is useful in a given situation.

Psychometric Soundness

Reliability measures how consistently a test measures what it's supposed to measure.
Validity assesses whether a test measures what it claims to measure.
Utility focuses on the practical value derived from test scores, specifically if it improves decision-making and is cost-effective.

Costs

Economic costs are financial expenses associated with testing, including:
- Purchasing tests
- Test administration materials
- Professional personnel costs
- Facility rental
- General business expenses
Noneconomic costs are intangible consequences, such as:
- Loss of public confidence due to inadequate testing
- Safety risks for workers and the public if testing is not conducted

Benefits

Economic benefits are financial gains from using a test, such as:
- Increased productivity leading to higher profits
- Improved quality control leading to less waste
- More efficient selection processes.
Noneconomic benefits include:
- Improved worker performance
- Reduced accidents
- Lower employee turnover
- A positive work environment

Utility Analysis

A utility analysis is a cost-benefit evaluation that determines the usefulness of an assessment tool.
It's not a single technique but a range of methods requiring different data inputs and producing varied outcomes.
Purpose of utility analysis: Determining if the benefits of a test outweigh its costs.

Expectancy Data

Expectancy tables provide the probability of a test taker achieving a specific score on a criterion measure.
They help determine if a test is effectively predicting desired outcomes and improving decision-making.

Taylor-Russell Tables

These tables estimate the improvement in selection outcomes when using a specific test.
They calculate the increased effectiveness of hiring decisions based on test scores.
