Document Summary
What is reliability: reliability whether a test, or whatever you use as a measurement tool, measures something consistently, consistency among scores, consistency among raters, consistency across time. Test-retest reliability: used when you want to examine whether a test is reliable over time. When you want to know whether a test is reliable over time. When you want to know if several different forms of a test are reliable or equivalent. When you want to know if the items on a test assess. Correlate the scores from a test given at time 1 with the same test given at time 2. Correlate the scores from one form of the test with scores from a second form of the same test of the same content (but not the exact same test). The bonzo test of identity information for adolescents is reliable over time. The two forms of the regular guy test are equivalent to each other and have shown parallel forms reliability.
