Chapter 6: Evaluating Selection Techniques and Decision Flashcards
the extent to which a score from a selection measure is stable and free from error
reliability
four ways to determine test reliability
- Test- Retest Reliability
- Alternate-forms Reliability
- Internal reliability
- scorer reliability
test- retest reliability
the extent to which repeated administration of the same test will achieve similar results
the consistency of test scores across time
temporal stability
bonus: the amount of anxiety an individual normally has all the time
trait anxiety
Bonus: anxiety has at any given moment
state anxiety
method of reliability in which two forms (Form A and Form B) of the same test are constructed, half of the sample receive form A and there other half receive form b
Alternate-Forms reliability
the extent to which two forms of the test are similar
form stability
the average correlation between alternate form of test used in the industry
.89
the extent to which the responses to the tests items are consistent
item stability
the extent to which test items measure the same construct
item homogeneity
the statistic used to determine the reliability of the tests that use items with dichotomous answers
Kuder- Richardson 20
a form of reliability in which the consistency of item responses is determined by comparing scores on half of the items with scores on the other half
split-half method
a statistic used to determine internal reliability of tests that use interval or ratio scales
coefficient alpha
the extent to which scorers agree on the test score, or the test is scored correctly
scorer reliability
