THIS STUDY WAS CONDUCTED TO (1) DETERMINE WHETHER DIFFERENCES IN TYPING TEST LENGTH, CONTENT, FORMAT, AND TIME LIMIT HAVE ANY EFFECT ON TEST SCORES, AND (2) COMPARE THE RELIABILITY OF 5-MINUTE TYPING TESTS WITH THAT OF 10-MINUTE TESTS. TWO EQUIVALENT FORMS OF THE U.S. EMPLOYMENT SERVICE TYPING TEST AND ONE FORM OF THE U.S. CIVIL SERVICE COMMISSION…

The development of perceptual-motor integration is an important area of study for the educational psychologist. This capacity is intimately or closely related to the development of reading and writing skills in children. This study reports a preliminary investigation of the reliability of one current test of this capacity, the Minnesota…

An overview of generalizability theory and a FORTRAN computer program for studying the generalizability of scores in a three facet, four factor design are presented. An illustrative example is presented. (Author/JKS)

An efficient algorithm for maximizing split-half reliability coefficients is described. Coefficients derived by the algorithm were found to be generally larger than odd-even split-half coefficients or other internal consistency measures and nearly as large as the largest split half coefficients. MSPLIT, Odd-Even, and Kuder-Richardson-20…

Shoemaker's conclusions related to the influence of various data base characteristics (reliability, variability of item difficulty indices, and degree of skewness in the normative distribution) on the standard error of a mean estimated via multiple matrix sampling procedures are examined. (Author/RC)

Considers both validity and reliability simultaneously in selecting the best short forms (SFs) of the Wechsler Adult Intelligence Scale-Revised (WAIS-R). Results indicate that incorporating reliability as a criterion has a dramatic impact on the obtained best SFs. (LLL)

Reports the validities and reliabilities of two short forms of the Wechsler Adult Intelligence Scale (Revised) (Vocabulary and Block Design, and Arithmetic and Picture Arrangement) for each of nine age groups, together with standard errors of estimate and measurement. Results support the use of these forms for their intended purpose. (BH)

A rationale for, and a relatively simple method of estimating the reliability of an observational method are described. A separate "reliability study," while not required, may be employed when examining data. Empirical findings show that high frequencies of occurrence are not necessary prerequisites for the reliable measurement of behavior.…

Results of this study indicate that the correlation between half-test scores over repeated splits, over persons, and over repeated testings resulting in different sets of observed scores, is given by Kuder-Richardson Formula 21. (RF)

This paper describes and compares procedures for estimating the reliability of proficiency tests that are scored with latent structure models. Results suggest that the predictive estimate is the most accurate of the procedures. (Author/BW)
