This report is the initial part of a 2-year study investigating first-year student attrition at Cuyahoga Community College (CCC). Of 388 students entering CCC in the fall of 1968, but not enrolling in the subsequent spring quarter, 146 (38%) supplied data on which the following results are based. A check of respondents' characteristics showed them…

Total circular triad scores (TCT) derived from the pair-comparison Minnesota Importance Questionnaire (MIQ) were used to study the relationship between inconsistency, and both internal consistency reliability and stability. Stability estimates (and Hoyt Coefficients) were computed for each of nine groups (retest internals from immediate retest to…

To study the relationship of education to economic growth for the state of Iowa, the hypothesis that increasing the level of education for the labor force would lead to higher levels of income or economic growth was tested for the period from 1950-1967. The Cobb-Douglas production was used to evaluate the relationship. The function used labor…

Using Project Talent and census data, estimates are made with a recursive model to explain scores on standardized tests, school continuation behavior, and lifetime income. Exogenous variables include socioeconomic backgrounds of students and their classmates, school spending, race, and region. The results suggest that: (1) school spending has its…

This paper reports on a study of the administrative behavior of school principals made through direct observation and a set of unique categories. Study objectives were to describe (1) the sources of principals' problems, (2) the principals' initial reactions to problem stimuli, (3) the patterns of principals' decisionmaking, (4) the premises…

Anticipated improvements in the educational level of the Nation's labor force, projected to the year 1985, are discussed and illustrated by tables and charts. These present data concerning the following: years of school completed by persons 25 years old and over in the civilian labor force, by sex and race, 1950 to 1985; projected educational…

The research reported is an attempt at construct validation of a proposed measure of administrator authenticity -- Seeman's scale of ambivalence toward leadership ideology. Seeman had implied that leaders who are more ambivalent would be less susceptible to reality distortion. Using Rokeach's dogmatism scale as an indicator of susceptibility to…

While current information on the dynamics of a library is essential, some concern has been expressed about the efficiency of the statistical collecting procedures as well as the usefulness of the statistical data collected at the Purdue University Libraries. Task priorities based on objectives and the significant cost factor of staff time, dictate…

THIS REPORT, WHICH CONSISTS OF A SERIES OF STATISTICAL TABLES, IS THE SEVENTH IN A SERIES THAT HAS BEEN PUBLISHED ANNUALLY BY THE MODERN LANGUAGE ASSOCIATION SINCE PASSAGE OF THE NATIONAL DEFENSE EDUCATION ACT OF 1958. TAKEN COLLECTIVELY, THE REPORTS CHART THE COURSE TAKEN BY FOREIGN-LANGUAGE STUDY IN THE NATION'S HIGH SCHOOLS FROM 1958 TO THE…

Reports a class exercise which requires students to recalculate the Chi-squares, t-tests, and one-way ANOVAs found in published psychological research articles. Describes students' reaction to the exercise and provides data on the 13% error rate they discovered. (Author/JDH)

The statistical properties of curriculum-based time-series data were investigated for 67 learning disabled students (grades 1-7). Results suggest that reading growth over time may be described by a negatively accelerated curve and that the statistical characteristics of time-series data are not necessarily independent in naturally occurring data.…

Demonstrates that some commonly used indices can be misleading in their quantification of reliability. The effects are most pronounced on gain or difference scores. Proposals are made to avoid sources of invalidity by using a procedure to assess reliability in terms of upper and lower limits for the true scores of each examinee. (Author/JDH)

The properties of nonmetric multidimensional scaling one explored by specifying statistical models, proving statistical consistency, and devloping hypothesis testing procedures. Statistical models with errors in the dependent and independent variables are described for quantitative and qualitative data. (Author/LMO)

An empirical method (PRESS) for examining and contrasting the cross-validated prediction accuracies of some popular algorithms for weighting predictor variables was advanced and examined. The sample specific PRESS method was suggested as most appropriate when selecting among several alternative weighting algorithms to achieve maximum…
