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…

A MEASURING OPERATION IS A SAMPLE FROM A UNIVERSE OF ADMISSIBLE OBSERVATIONS....GENERALIZABILITY STUDIES ESTIMATE THE MAGNITUDE OF THE DISCREPENCIES LIKELY TO ARISE UNDER A GIVEN MEASURING PROCEDURE, AND PROVIDE FORMULAS FOR ESTABLISHING INTERVAL AND POINT ESTIMATES OF THE UNIVERSE SCORE. A MULTIFACET GENERALIZABILITY ANALYSIS DEPARTS IN SEVERAL…

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)

In this brief note, the author argues against the use of squared correlation coefficients as measures of explained variance. (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)

Multivalent relations, inferred as relationships with an added dimension of discernment, are realized as weighted graphs with multivalued edges. A unified treatment of the threshold problem is discussed and a reliability measure is produced to judge various partitions. (Author/EM)

Notes that, while researchers seek accurate causative factors for suicidal behavior, validity and reliability of certification of suicide deaths by coroners and medical examiners have been questioned. Provides overview of existing vital statistics registry system, proposes innovations that could improve quality of officially reported suicide…

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)

An adjustment to the Rand statistic, which will allow comparison across different levels for number of clusters found within a classification, is proposed. This adjustment permits the user to compare several different classifications with respect to classification agreement, while correcting for the contribution of chance to any observed…
