Study Notes

Utility Analysis

Taylor-Russell tables and Naylor-Shine tables can be used for utility-related decisions, especially for employment tests and selection ratios.
Taylor-Russell tables estimate the percentage of future employees who will be successful, based on three components: validity, base rate, and selection ratio.
Limitations of Taylor-Russell tables include only being applicable to interval data and difficulty in determining "successful" and "unsuccessful" employees.

Naylor-Shine Tables

Naylor-Shine tables calculate the difference between the means of selected and unselected groups to derive an index of the test's added value to established procedures.

Brogden-Cronbach-Gleser Formula

The formula estimates the dollar amount of utility gain resulting from the use of a particular selection instrument under specified conditions.
Utility gain refers to the estimated benefit (monetary or otherwise) of using a particular test or selection method.

Cut Scores

Norm-referenced cut scores are set with reference to the performance of a group, dividing data into two or more classifications.
Fixed cut scores, also referred to as absolute cut scores, are set with reference to a judgment concerning a minimum level of proficiency required.
Multiple cut scores are used to categorize test-takers with reference to one predictor.

Multistage Selection Process

Each stage has a cut score designed to ensure applicants possess a minimum level of a specific attribute or skill.
Multiple hurdles are part of a multistage decision-making process where achieving a particular cut score on one test is necessary to advance to the next stage.

Compensatory Model of Selection

High scores on one attribute can compensate for low scores on another attribute in this model.

Decision Theory and Test Utility

Base rate, hit rate, miss rate, false positive, and false negative are important concepts in decision theory and test utility.
Base rate is the proportion of true cases in a population, and the hit rate is the proportion of true cases detected by a test.
False positives and false negatives can occur, and the goal is to achieve a high hit rate and minimize false positives/negatives.

Proportion of Correct Decisions

The proportion of correct decisions with a test is calculated by adding correct rejections and correct acceptances and dividing by the total employees.
Baseline correct decisions are calculated by dividing successful employees by total employees.
