Data from a total of 6,726 evaluation forms collected over three terms supplied information concerning instructors and courses. Items on the evaluation forms were separated into five factors. The variance-covariance matrix of these factors for each class was compared with the combined variance-covariance matrix of the other classes taught by the…

Statistical data of an educational quality assessment for the Pennsylvania State Department of Education are presented. The ten goals listed, for grade level five, cover the areas of: 1. Self Understanding; 2. Understanding Others; 3. Basic Skills: Verbal and Basic Skills: Math; 4. Interest in School; 5. Citizenship; 6. Health Habits; 7.…

The Schools and Staffing Survey (SASS) is an integrated system of surveys of public and private schools, school districts, school administrators, and teachers conducted by the National Center for Education Statistics (NCES). This collection contains papers related to the SASS presented at meetings of the American Statistical Association in August…

Electricity conservation programs were implemented in matched pairs of office-classroom-laboratory buildings and dormitories. The methodological problems of predicting consumption levels, interpreting why changes in consumption occurred, and estimating initial waste levels are discussed along with their implications for the conduct of behavioral…

Subjective norms account for a significant, albeit small, proportion of unique variance in intentions. To explore the hypothesis that this effect can be explained largely by individual differences in the degree to which people are apt to be more under normative control, subjects were asked to indicate their intentions, attitudes, and subjective…

Increasingly, unpopular facilities are sited in sparsely populated areas for which data are unavailable. The Local Expert Procedure (LEP) estimates selected demographic characteristics of small, rural areas by combining the housing unit method of population estimation with random sampling and key informant ethnography. Factors affecting the…

This article shows how the methods of survival analysis (also known as event history analysis) lend themselves to the study of the timing of educational events. Using examples from teacher attrition and student dropout research, survival methods are introduced for building statistical models of the risk of event occurrence over time. (Author/SLD)

This paper recommends use of analysis of covariance in early intervention research to account for pretreatment group differences and increase statistical power. Diagrams show how analysis of covariance manipulates data under various conditions. Simulated data analysis demonstrates the process of selecting covariates and shows the results with and…

Error profiles for the Fall Enrollment Survey of the Higher Education General Information Survey (HEGIS) were developed as part of an assessment of the quality of survey data. Three statistics were of particular interest: the count of full-time equivalent students, the breakdown by race/ethnicity, and the count of unclassified students. Attention…

Sampling distributions for ten tests for comparing population variances in a two group design were generated for several combinations of equal and unequal sample sizes, population means, and group variances when distributional forms differed. The ten procedures included: (1) O'Brien's (OB); (2) O'Brien's with adjusted degrees of freedom; (3)…

How accurately deltas (statistics measuring the difficulty of items) established by pre-test populations reflect deltas obtained from final form populations, and the consequent utility of pre-test deltas for constructing final (operational test) forms to meet developed statistical specifications were studied. Data were examined from five subject…

Three statistical problems related to criterion-referenced testing are investigated: estimation of the likelihood of a false-positive or false-negative decision with a mastery test, estimation of true scores in the Compound Binomial Error Model, and comparison of the examinees to a control. Two methods for estimating the likelihood of…

Five data collection techniques and two sampling methods were examined in terms of costs, rates of return, quality of the data collected, and degree of representativeness in assessing needs and interests of public television viewers in rural areas. Data collection techniques were (1) mail only, (2) mail incentive, (3) telephone only, (4) mail and…

Two sampling designs were compared for the planned 1978 national longitudinal survey of high school seniors with respect to statistical efficiency and cost. The 1972 survey used a stratified two-stage sample of high schools and seniors within schools. In order to minimize interviewer travel costs, an alternate sampling design was proposed,…

A stratified two-stage cluster sample design was chosen for the Texas Assessment Project and is described in this document. The sample was designed so as to achieve a chosen level of precision in item analysis data within each of the 20 geographic regions chosen for analysis. Four sampling frames were developed: 9-year-olds; sixth graders;…
