The nature of the criterion (dependent) variable may play a useful role in structuring a list of classification/prediction problems. Such criteria are continuous in nature, binary dichotomous, or multichotomous. In this paper, discussion is limited to the continuous normally distributed criterion scenarios. For both cases, it is assumed that the…

Determination of statistical power for analysis of variance procedures requires five elements: (1) significance level; (2) effect size; (3) number of means; (4) error variance; and (5) sample size. Significance levels are traditionally chosen to be 0.5, .01, or .001. Effect size is not discussed in this paper. The number of means is determined by…

Monte Carlo studies explored the sampling characteristics of Cohen's d and three approximations to Cohen's d when used as average effect size measures in meta-analysis. Reviews of 10, 100, and 500 studies (M) were simulated, with degrees of freedom (df) varied in seven steps from 8 to 58. In a two independent groups design, samples were obtained…

This study used multiple regression analyses to identify the socioeconomic, demographic and attitudinal correlates of neighborhood differences in the rate of child abuse and neglect. Comparison of actual vs. predicted rates defined high- and low-risk neighborhoods. These "risk scores" then become variables for inclusion in additional…

Statistical analysis of election results from four California counties over a twenty-year period (1956-1977) shows that the defeat of an incumbent school board member in one election increases the probability of incumbent defeats in the next three elections in the same district, while decreasing the probability of incumbent defeats in that…

The Goodman technique of log linear analysis is ideal for family research, because it is designed for categorical (non-quantitative) variables. Variables are dichotomized (for example, married/divorced, childless/with children) or otherwise categorized (for example, level of permissiveness, life cycle stage). Contingency tables are then…

The goal of this paper was to develop a theory of organization/environment interaction by examining the impact of perceived environmental uncertainty on organizational processes and on organizational goal attainment. It examines theories from the organizational environment literature and derives corollaries that are empirically tested using a data…

THIS DOCUMENT IS SECTION 1 OF A 3-PART REPORT BY THE EDUCATIONAL TESTING SERVICE. THIS SECTION DESCRIBES, IN EXTENSIVE STATISTICAL TERMS, A SAMPLE OF 445 HEAD START CHILDREN IN TERMS OF THEIR SCORES ON (1) THE STANFORD-BINET L-M, (2) THE CALDWELL PRESCHOOL INVENTORY, AND (3) THE PROJECT HEAD START BEHAVIOR INVENTORY. THE SAMPLING PROCEDURES USED…

Increasing interest over the last twenty years in quality Greek and Latin translations seems to be primarily a reflection of the "paperback revolution." Figures and trend reports from various publishers illustrate the burgeoning numbers of classical works in translation. This new availability has enabled students of literature, history, political…

A project was undertaken at Florida Technological University in 1974-75 to establish a procedure for determining discipline productivity factors for the internal allocation of instructional faculty resources. A theoretical model for faculty allocation was developed, independent of discipline, and student credit-hour productivity factors were…

A State-wide followup, personal interview survey was made of 1,396 Virginia vocational agriculture graduates, from the classes of 1968 through 1972 and representing 34 percent of the total, to ascertain the percentage who made use of 144 content items usually taught in vocational agriculture, and whether used items were used on- or off-the-job.…

This statistical report presents raw data and analyses in three parts: (1) a compendium of census data by district boundaries; (2) statistical analyses of all variables, including means, standard deviations, and ranges; and (3) relationship analyses among all variables, census and school districts. Included in the appendix are a list of school…

The purpose of this paper is to define the framework within which empirical investigations of probabilistic grammars can take place and to sketch how this attack can be made. The full presentation of empirical results will be left to other papers. In the detailed empirical work, the author has depended on the collaboration of E. Gammon and A.…

This report, the third of a series of reports dealing with convergent communication among children, compares children's performance on certain communication tasks with that of adults. (Convergent communication is defined as communication in which two persons cooperatively exchange information in order to reach an explicitly stated goal and where,…

This paper reports the initial phase of a series of experiments conducted on a large number of videotapes made for the purpose of analyzing public-school classroom interaction. The experiments originally aimed to preduct the most reliable, efficient and economic way of producing transcriptions which are sufficiently representative of the verbal…
