The professional orientation difference approach was operationalized as a stress on the importance of intellectual activity, autonomy, service and influence, with de-emphasis on the monetary, prestige, security and human relations aspects of a job. As a difference score, the index was subject to special reliability problems. This analysis…

The purpose of this study was to present an empirical correction of the KR21 (Kuder Richardson test reliability) formula that not only yields a closer approximation to the numerical value of the KR20 without overestimation, but also simplifies computation. This correction was accomplished by introducing several correction factors to the numerator…

The Beery Test of Visual Motor Integration was utilized in a reliability study with elementary school children. The results indicate sufficient scorer reliability and stability over time to merit its use with young children. (Author)

The purpose of this paper is to prove that one currently recommended method of obtaining the reliability of an instrument defined on a population of aggregate units is invalid. This method randomly splits the aggregate into two halves, correlates the two half unit scores by a Pearson product moment correlation coefficient, and corrects the…

This investigation dealt with the development and evaluation of both a music dictation test (PRM78 Dictation Test) and a sightsinging test (CSS76 Criterion Sightsinging Test). It was hoped that the dictation test could eventually be developed to serve as an adequate replacement for the latter. Thirteen samples participated in this project--7…

Results obtained by the Kudar-Richardson formula (20) adapted for use with R-KW scoring are compared with three other reliability formulas. Based on parallel tests administered at the same sitting the KR (20) estimates are compared with alternate-form correlations and with odd-even correlations adjusted by the Spearman-Brown prophecy formula.…

Data from 200 college-level tests were used to compare three reliability approximations (two of Saupe and one of Cureton) to Kuder-Richardson Formula 20 (KR20). While the approximations correlated highly (about .9) with the reliability estimate, they tended to be underapproximations. The explanation lies in an apparent bias of Lord's approximation…

In this speech given at the 1976 annual breakfast of the National Council on Measurement in Education Dr. Thomas J. Fitzgibbon, outgoing president of NCME, responds to critics of standardized testing and outlines the correct uses for it. He believes that many criticisms of standardized testing are due to misunderstanding or a lack of information.…

A FORTRAN program for clustering variables using the alpha coefficient of reliability is described. For batch operation, a rule for stopping the agglomerative precedure is available. The conversational version of the program allows the user to intervene in the process in order to test the final solution for sensitivity to changes. (Author/JKS)

This program computes specific category agreement levels for both nominally and ordinally scaled data. For ordinally scaled data, an option is available for collapsing the original scale to a smaller number of categories, with the goal of improving the level of interrater reliability for the rating scale.

Designed to measure self-actualization as defined by Abraham Maslow, the Jones Self Actualizing Scale, as assessed in this study, possesses content validity, reliability, and a number of other positive characteristics. (JC)

When raters in a reliability study are a random sample, inferences about the intraclass correlation coefficient must be based on three mean squares from the analysis of variance: between subjects, between raters, and error. An approximate confidence interval for the parameter is presented as a function of these mean squares. (Author/JKS)
