Describes and compares eight methods of estimating the parameters of the Zipf distribution. (CLB)

This chapter outlines the theory of cost-benefit analysis and discusses its application to determining the cost-benefit of instructional development projects. Three types of applications are discussed: (1) descriptive applications of single projects; (2) predictive studies of proposed projects; and (3) comparative analysis of alternative projects…

Two sophisticated--autoregressive integrated moving average (ARIMA), straight-line regression--and two naive--simple average, monthly average--forecasting techniques were used to forecast monthly circulation totals of 34 public libraries. Comparisons of forecasts and actual totals revealed that ARIMA and monthly average methods had smallest mean…

Addresses the utility of a noninvasive measure of cardiac vagal tone in predicting developmental outcome among infants at risk for cognitive disabilities. Results suggest that measurement of cardiac vagal tone may provide an important means for assessing risk in birth-stressed populations. (Author/RH)

Two models of library circulation, the Markov model and the mixed Poisson Model, are applied to circulation statistics from the University of Saskatchewan. Goodness-of-fit tests indicate that neither model fits the data; in both cases, the set of noncirculating items is larger than that predicted by the model. (Author/LRW)

Composite scores for 51 gifted children (ages 3-12) on the Stanford-Binet LM were found to be significantly higher than scores on the Stanford-Binet 4th Edition. Correlations between the LM total and 4th Edition area scores were significant. Results suggest that the 4th Edition composite score cut-off value for assessing giftedness may require…

A test of predicted anxiety which focused on public speaking was given before and after two life skills courses in an English college. The students' own reports and observations by the author supported the results, which indicated a reduction of anxiety in the course which used simulations. (Author/LRW)

Data from the Cooperative Institutional Research Program Follow-Up Surveys were used to study student retention at four-year colleges and universities. Data used were from the 1985-1988 follow-up surveys of 1981-1984 freshmen. Student data were also requested directly from the institutions themselves, concerning degree earned, number of years…

The York Region Board of Education in Ontario, Canada, screens students for giftedness in grade 3. This report analyzes data produced in the 1986-87 screening procedure, involving approximately 3,400 students. The report begins with a review of procedural changes that were designed to make the screening more effective and efficient than earlier…

This study examined the relationship and relative importance of selected variables to successful performance of urban community college students on the American College Testing Program (ACT) College Outcome Measures Program (COMP). The importance of age, race, gender, type of degree, program or major category, admissions criteria and ACT…

This paper examined test scores and information about test takers collected from the Graduate Record Examination (GRE) national test administration files, GRE validity study data provided by institutional users, and survey questionnaires sent to test repeaters. Data were collected from 200,000 men and women who took the GRE General Test in June…
