In order to determine the comparability of the IQ estimates and subtest scores on the Wechsler Intelligence Scale for Children (WISC) and the Wechsler Intelligence Scale for Children--Revised, both tests were adminstered in a four-cell counter-balanced design. Overlapping items were given only once. Subjects were 77 male and 51 female adolescents…

This study develops a self-report inventory of public speaking apprehension that establishes measures of content, construct, and predictive validity. An item pool was generated by students that were anxious about giving speeches, and the resulting instrument was then administered to the general student population and factor analyzed. Each factor…

One of 52 theoretical papers on school crime and its relation to poverty, this chapter focuses solely on changes in student crimes in the period from 1950 to 1975. A number of observations are made about student violence. First, assaults against teachers have increased sharply in the past 25 years in absolute numbers, but not in the percent of…

Selected findings are presented from the National Prisoner Statistics (NPS) program, a survey of both inmates in state and federal prisons, and the National Crime Survey (NCS), a survey of victims of crime. Certain conventional beliefs or myths about the nature of crime in the United States are challenged by providing the statistical realities.…

Methods are described for constructing Resolution IV Screening designs that are robust to linear, quadratic, and cubic trend effects and will also keep the number of factor-level changes for some variables at a minimum. Complete designs, capable of screening up to 32 variables, are provided along with appropriate methods of analysis. Numerous…

This study was conducted to analyze and summarize raw data obtained from a 1972 study: "Report on a Cost Study of Specific Technical Processing Activities of the California State University and College Libraries" with the hypothesis that the cost of technical processes increases as the production volume both rises above and falls below…

Five papers published in a special edition of Human Factors, August 1973 are examined in an attempt to explain and illustrate the characteristics and applications of central-composite designs in the context of response-surface methodology (RSM). A detailed analysis is provided to show that the experimental papers (1) fail to illustrate the most…

To the data analyst, outliers can present both a problem and an opportunity. Stray or outlying observations can severly distort estimates of a distribution's central tendency (like the mean) and estimates of one variable's relationship to another (like the regression coefficient). These problems are frequent and serious, and as a result,…

The relationship between education and job satisfaction has not been sufficiently well documented to qualify as unquestionable. Published research on the subject either fails to adequately assess the influence of education on job satisfaction or is too occupationally and/or geographically limited to form the basis for generalization. To examine on…

Reported research uses stepwise multiple regression analyses to generate regression equations for 60 school age subjects with choice of right action and stage of moral reasoning on moral dilemmas as the dependent variables. Age, IQ, socioeconomic status, awareness of consequences, empathy, and mean moral maturity scores were used as predictor…

This paper describes the proposed Assessment Center at Mercy College in Dobbs Ferry, New York. The center is intended to provide statistical and technical support for the Mercy College elementary education, special education, and speech and hearing departments in the areas of student assessment, student guidance, and program evaluation. Evaluation…

This study attempts to examine and document the implementation pattern of Individually Guided Education (IGE) across 30 Wisconsin school districts operating IGE programs in their schools. Using these results, the data were then analyzed to determine which of the seven IGE components examined, contributed most to a favorable overall or Total IGE…

The results of an algorithm which is designed to take a set of commonality coefficients, either real or manipulated, and, if possible, produce one or more sets of regressor correlations that are consistent with them are examined. A number of different ways of resolving the higher order commonality values into their lower orders were tried and the…

A graph-theoretic paradigm is used to generalize the common measures of categorical clustering in free recall based on the number of observed repetitions. Two graphs are defined: a graph G that characterizes the a priori structure of the item set defined by a researcher, and a graph R that characterizes a subject's protocol. Two indices of…

In this paper 12 blind transformation procedures are applied to 18 data sets. The results of the analyses indicate that the orthotran transformation solution is not restricted to particular types of data as are so many other transformation solutions. The evidence presented in this paper strongly suggests that the orthotran solution must be…
