Missouri implemented a new statewide funding formula based on the Outstanding Schools Act in 1993 to increase equity in school finance. This study examined the impacts of the new foundation funding formula on finance equity compared with the selected equity indices including range, restricted range, coefficient of variation, federal range ratio,…

Risks of life on the street caused by inclement weather, harassment, and assault threaten the unsheltered homeless population. We address some challenges of enumerating the street homeless population by testing a novel capture-recapture (CR) estimation approach that models individuals' intermittent daytime visibility. We tested walking and…

Discusses normalization features of good concentration measures and extends the range of values of concentration measures that are population-size-independent. Rational normalization is described, and mathematical formulas for the coefficient of variation, Pratt's measure, the Gini index, Theil's measure, and Atkinson's indices are explained. (14…

In rebuttal to a critique of the authors' examination of prevalence rate variability for special education categories, it is claimed that a consideration of the nature of prevalence rate data, the correct use of inferential statistics, and the coefficient of variation itself, suggest the objections are not justified.

The voice quality of individuals with Down Syndrome (DS) is generally described as husky, monotonous and raucous. On the other hand, the voice of DS children is characterized by breathiness, roughness, and nasality and is typically low pitched. However, research on phonation and intonation in these participants is limited. The present study was…

Product correlation was studied under the condition that the original variables are jointly distributed multivariate normal with equal coefficients of variation. Product correlation was shown to range between the two extremes of sum correlation and either the value zero or an unfamiliar function of the intercorrelations of the original variables.…

According to empirical evidence and noted implications of sustainable agricultural development as a systemic and multi-actor process, integration of the research function of higher agricultural education in Iranian agricultural research systems seems to be an ongoing and considerable necessity. With the aim of identification and analysis of…

A pervasive hypothesis in the timing literature is that temporal processing in the milliseconds and seconds range engages the basal ganglia and is modulated by dopamine. This hypothesis was investigated by testing 12 patients with Parkinson's disease (PD), both "on" and "off" dopaminergic medication, and 20 healthy controls on three timing tasks.…

A multitude of methods has been proposed to estimate the sampling variance of ratio estimates in complex samples (Wolter, 1985). Hansen and Tepping (1985) studied some of those variance estimators and found that a high coefficient of variation (CV) of the denominator of a ratio estimate is indicative of a biased estimate of the standard error of a…

Examines intrastate equality in educational resource allocation from 1980 to 1987, using school district data on instructional expenditures per student to calculate Gini and Theil coefficients of variation for 1980 and 1987 and make appropriate comparisons. A majority of states have a more equal distribution of instructional expenditures in 1987…

In a study of development of automaticity in second-language word recognition, 105 English-speakers speaking French performed multiple lexical-decision tasks, and differences in coefficient of variation of lexical decision reaction time were compared cross- sectionally and longitudinally. Results confirm that with extended learning experience, the…

Reviews the school-level resource-allocation literature and presents findings of a study of school-district expenditures in Chicago, Forth Worth, New York, and Rochester. Horizontal equity results show that in Chicago, New York, and Fort Worth, most coefficients of variation are below 0.15. Rochester's system is slightly less equitable. For…

A meta-analysis of the reliability of the scores from a specific test, also called reliability generalization, allows the quantitative synthesis of its properties from a set of studies. It is usually assumed that part of the variation in the reliability coefficients is due to some unknown and implicit mechanism that restricts and biases the…

This research examined the level of equity of the public school funding system in Texas that in September of 2004 was held to be unconstitutional by a state district judge. The study also introduces a mechanism, referred to as the Revenue-to-Population Index or RTP Index, which compares funding equity within the unconstitutional system among 1031…

A cylinder rolling down an inclined board is a commonly seen and interesting object to study and it is also easy to experiment with and model. Following what has become a popular practice, we use smartphones to measure the angular acceleration of a cylinder rolling down a plane of different inclining angles. The friction force deviates from the…
