The non-response bias analysis of data from a stratified nationwide probability sample of high school seniors produced evidence in support of the hypothesis that nonrespondents tend to be of lower "educational level" than respondents. A partial-response bias analysis of the same data indicated that there were similarities between the biases of…

Computes various thermodynamics and statistical quantities of all electrically charged particles in a small plasma to analyze: (1) How many particles are required for computer stimulation of a macroscopic plasma? (2) To find out if this method is accurate and fast enough to become a good tool of statistical plasma mechanics. (GA)

The influences of class size and the number of students completing surveys on faculty and course ratings were studied. For classes of 30 or more, a 50 percent response rate gives an acceptable indication of rating, while for a class of less than 30, about 80 percent return is needed. (Author/SW)

Using observational data on classroom teachers, statistical procedures are presented for studying two questions on the stability of teacher behavior over time: (1) Is the individual teacher's behavior consistent? and (2) Are individual differences among teachers consistent? Approaches and methods of previous temporal stability studies are…

Examines data analysis at three levels: analysis of data; secondary analysis is the re-analysis of data for the purpose of answering the original research question with better statistical techniques, or answering new questions with old data; and, meta-analysis refers to the statistical analysis of many analysis results from individual studies for…

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…

Illustrates how the combined use of qualitative and quantitative methods were necessary in obtaining a clearer understanding of the process of incest in American society. Argues that the exclusive use of one methodology would have obscured important information. (FMW)

Discusses issues involved with selecting a methodology and data analysis technique for studying divergent views of the family. Qualitative and quantitative methods, and linear and nonlinear models, are described. Statistical and theoretical issues regarding the use of discrepancy scores are examined. (BC)

Examines the manner in which the data-driven character of child development research limits the validity and penetration of the search for new knowledge and understanding, and imposes a skewed image of what is known about children and childhood by excluding the less objective observations and insights of the clinicians and practitioners.…

A new report published by the Manhattan Institute for Education Policy, "The Effect of Special Education Vouchers on Public School Achievement: Evidence from Florida's McKay Scholarship Program," attempts to examine the complex issue of how competition introduced through school vouchers affects student outcomes in public schools. The…

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)…

All social science serves some agenda: social science research is a value-bound, value-determined, context-situated, and ideologically loaded enterprise. Each researcher makes choices in the following areas, whether tacitly, implicitly, or deliberately: (1) a paradigm choice, either conventional (rationalistic) or emerging (naturalistic); (2) the…

The purpose of this research study was to assess item response model-test data fit using residuals. First, a comparison of raw and standardized residuals for describing model-test data fit was carried out. Second, hypotheses concerning the relationship between residual sizes and several item characteristics were studied. The analyses with…

The major finding of the Law-Related Education Evaluation Project report for Year 1 (1981), that law-related education courses can reduce juvenile delinquency, is of limited use to educational decision makers and could be misleading. The research design leaves much to be desired; however, that fact must be considered in light of the difficulty of…
