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