Kelly's formula estimates sampling variance of correlation corrected for attenuation by using split-half reliabilities. In some cases, coefficient alpha estimate of reliability is preferable. A simulation study suggests a variation of Kelly's formula can be used appropriately with coefficient alpha. Kelly's formula is modified to accept…

Eight asymptotically robust tests of population correlation coefficient equality are proposed and are studied along with two parametric tests. Monte Carlo simulation is used to compare the small sample performance of these ten procedures. The sampled distributions consist of the normal distribution, two mixed normal distributions and four…

This study investigates four widely used methods of collecting direct similarity judgments for nonmetric multidimensional scaling: rating scale, triads, rank order of pairs, and conditional rank order. (Author/PN)

Analyzes press coverage of the 1979 British general election to determine if reporting concentrated on the "dramatic contest" aspects of the campaign or on issues. Concludes that while coverage of the "dramatic contest" aspects of the election increased as the campaign went on coverage of the issues remained the major focus.…

Indicates that the Rix modification of the Lix Readability Formula is easy to calculate, correlates highly with other popular formulas, and is useful for materials for grades 3 through 12. (AEA)

Two tests were created from a standardized reading achievement test and vertically equated using a sample of third and fourth grade students. Based on differences in ability estimates for the same student, the Rasch model did not provide a satisfactory means of vertical equating. (Author/CM)

Monte Carlo methods are used to explore the accuracy of a method for establishing confidence intervals for variance component estimates in generalizability studies. Previous research has shown that variance component estimation errors due to sampling are often larger than suspected. (Author/CM)

The National Longitudinal Survey of Labor Force Behavior concluded that underprivileged youth lack occupational information. But the Knowledge of the World of Work Test administered to the young people surveyed does not appear to be reliable. (SK)

The factorial validity and internal consistency reliability of the Devereux Elementary School Behavior Rating Scale were examined with a random sample of elementary school children. Given the problem of multicollinearity that was shown to exist among subscales, the authors suggest caution in the interpretation of Devereux subscales as discrete…

The Revised Children's Manifest Anxiety Scale was administered to 534 children (grades 4-6) at the beginning and end of the school year. The total anxiety score correlated .68 across the nine-month period, supporting the temporal stability of the test. (Author/BW)

Results in the engineering literature on "k out of n system reliability" can be used to characterize tests based on estimates of the probability of correctly determining whether the examinee knows the correct response. In particular, the minimum number of distractors required for multiple-choice tests can be empirically determined.…

Two hundred seventy-four boys and girls, aged 7 through 15 years, participated in a test-retest reliability study of the Developmental Tests of Visual-Motor Association. Test-retest correlations for the total group and subjects comprising categories A through D were significant. (Author/SJL)

The purpose of this article is to review applications of reliability formulas and to recommend more appropriate methods of determining the reliability of affective instruments. (SK)

Formulas for the standard error of measurement of three measures of change (simple differences; residualized difference scores; and a measure introduced by Tucker, Damarin, and Messick) are derived. A practical guide for determining the relative error of the three measures is developed. (Author/JKS)

This paper examines the properties of the Item Efficiency Index proposed by Neill and Jackson (1976; EJ 137 077) for minimum redundancy item analysis. (Author/BW)
