Evaluating Selection Techniques and Decisions Flashcards
The extent to which a score from a test or from an evaluation is consistent and free from error
Reliability
The extent to which repeated administration of the same test will achieve similar results
Test-retest reliability
The consistency of test scores across time
Temporal stability
The extent to which two forms of the same test are similar
Alternate-forms
reliability
A method of controlling for order effects by giving half of a sample Test A first, followed by Test B, and giving the other half of the sample Test B first, followed by Test A
Counterbalancing
The extent to which the scores on two forms of a test are similar
Form stability
The extent to which responses to the same test items are consistent
Item stability
The extent to which test items measure the same construct
Item homogeneity
A statistic used to determine internal reliability of tests that use items with dichotomous answers (yes/no, true/false)
Kuder-Richardson Formula 20 (K-R 20)
A form of internal reliability in which the consistency of item responses is determined by comparing scores on half of the items with scores on the other half of the items
Split-half method
Used to correct reliability coefficients resulting from the split-half method
Spearman-Brown
prophecy formula
A statistic used to determine internal reliability of tests that use interval or ratio scales
Coefficient alpha
The extent to which two people scoring a test agree on the test score, or the extent to which a test is scored correctly
Scorer reliability
The degree to which inferences from test scores are justified by the evidence
Validity
The extent to which tests or test items sample the content that they are supposed to measure
Content validity
The extent to which a test score is related to some measure of job performance
Criterion validity
A measure of job performance, such as attendance, productivity, or a supervisor rating
Criterion
A form of criterion validity that correlates test scores with measures of job performance for employees currently working for an organization
Concurrent validity
A form of criterion validity in which test scores of applicants are compared at a later date with a measure of job performance
Predictive validity
