Reliability and Confidence.
Test Service Bulletin, n44 p2-7 May 1952
Some aspects of test reliability are discussed. Topics covered are: (1) how high should a reliability coefficient be?; (2) two factors affecting the interpretation of reliability coefficients--range of talent and interval between testings; (3) some common misconceptions--reliability of speed tests, part vs. total reliability, reliability for what group?, and test reliability vs. scorer reliability; and (4) a practical checklist.
