Abstract

Precision is a key facet of test development, with score reliability determined primarily according to the types of error one wants to approximate and demonstrate. This article identifies and discusses several primary forms of reliability estimation: internal consistency (i.e., split-half, KR-20, α), test-retest, alternate forms, interscorer, and interrater reliability.
Internal consistency reliability test-retest reliability
