Investigates the relationships between the parameters of the Simon-Yule model and the shapes of three bibliometric distributions: Lotka's Law of Scientific Productivity; Bradford's Law of Bibliometric Scattering; and Zipf's Law of Word Frequency. The results indicate that the probability of a new entry determines the characteristics of all three…

A pivotal theorem which is of critical importance to statistical inference in probability and statistics is the Central Limit Theorem (CLT). The theorem concerns the sampling distribution of random samples taken from a population, including population distributions that do not have to be normal distributions. This paper contains a brief history of…

Practical formulas for several analysis of variance (ANOVA) designs and models are presented which make it possible for readers to compute strength of association measures without the use of complete ANOVA tables. (Author/PN)

Methods are described for obtaining upper and lower bounds to both false-positive and false-negative decisions with a mastery test. These methods make no assumptions about the form of the true score distribution. (CTM)

Modifications to current methods of calculating and reporting financial ratios are outlined for college managers. The modified ratios, felt to be more realistic, are illustrated with applications in three areas: (1) student revenues; (2) endowment and other investment income; and (3) public and private gifts, grants, and contracts revenue. (MSE)

Compa-ratio, a technique used in diverse ways in the corporate sector, was used to analyze gender bias in faculty salaries at one university. Results, compared with those derived from two multiple regression analyses of the same data, suggest that the technique is adaptable for higher education and easily understood by administrators and faculty.…

Discusses science evaluation studies that seek to determine quantitatively the contribution of different authors, departments, or countries to the whole system, and suggests that different scoring methods can yield totally different rankings. Presents formulas for counting procedures, nontrivial examples of anomalies, and possible solutions.…

Provides an introduction to structural equation modelling (SEM) for language research, including: general objectives of SEM applications relevant to language assessment; methodology and statistical assumptions about data that must be met; commonly-used SEM steps and concepts; application matters, with sample models; and recent critical discussions…

According to a formula developed to measure the adequacy of state educational finance levels, only three of six selected midwestern states provided adequate levels of expenditure per pupil in 1981-82. The formula for determining adequacy, developed by Jerry Miner and Walter McMahon, consists of totaling adequate levels of expenditure in seven…

Statistical and budgeting techniques used in several institutions to measure productivity are described and illustrated. The analyses include both moment-in-time cost versus productivity and program trends. (MSE)

In two treatment-repeated measurements designs, the ratio between the unbiased variance of the differences and twice the variance of the errors of measurement can be used to test for interaction of subjects and treatments. The use of this statistic is illustrated. (Author/CP)

Proposes a model for technical journal deselection based on the Bradford law of distribution. The model's operational prescriptives, characteristics of the Bradford distribution in the field of pediatrics, and relevance to collection management are discussed. (42 references) (KRN)

Studies the performance of probabilistic information retrieval systems using differing statistical dependence assumptions when estimating the probabilities inherent in the retrieval model. Experimental results using the Bahadur Lazarsfeld expansion on the Cystic Fibrosis database are discussed that suggest that incorporating term dependence…

Direct and indirect effects in decomposed zero-order correlations among variables in causal models are considered. Under certain circumstances, the components of the decompositions could be interpreted as direct, indirect, and spurious causal effects, plus a component called joint associations. The sum of the direct and indirect effects is the…

Two procedures for systematic organizational quality assessment are presented: (1) a distributional assessment to monitor individual, group, or unit performance by establishing real and maximum-feasibility parameters; and (2) a cost-assessment system based on utility analysis, to assign dollar values and benefits to quality interventions targeting…
