Administering a test to a group of individuals, then computing the average intercorrelation among all items on the test demonstrates the _________ method of estimating reliability.
A) test-retest
B) alternate forms
C) split-half
D) internal consistency

Question

Quizplus · Accepted Answer

The method described is computing internal consistency reliability, which examines the extent to which all items on a test measure the same construct. Test-retest reliability involves administering the same test to the same group at two different time points to see if scores are consistent. Alternate forms reliability involves administering two different but similar versions of a test to the same group and comparing scores. Split-half reliability involves splitting a test into two halves and seeing if scores are consistent between the halves.
