The Minnesota Child Development Inventory was used to obtain parent observations on 59 children before the start of the kindergarten year. Results indicated that the parent report on a number of variables from the MCDI correlated highly with postkindergarten success in reading. (Author)

This material demonstrates the usefulness of an accurate space utilization analysis drawing inference from utilization statistics. (Author)

Research findings disclose the need for improvement of discrepancies discovered to exist between the role perceptions of faculty members and organizational goals of a Pennsylvania community college. Suggests the development of a sensitive screening instrument, or some means of educating faculty to the purposes of the 2-year college. (Author/JN)

Analysis of the data from a survey of members of a university faculty and of student attitudes toward this faculty indicate no relationship between student-rated adequacy of teaching and the extent of a teacher's scholarly activity.

Six suggestions offered to sociologists obligated to teach statistics to undergraduates in sociology programs. (Editor)

The results of reanalyses of statistical procedures used in the class-size meta-analyses by Glass and Smith are reported. The analyses suggest that the use of suboptimal statistical methods did not greatly affect the results of the meta-analyses by Glass and Smith. (Author/PN)

Rules are given for estimating accuracy of predictions based on a multiple regression equation. Formulas for moments of distribution and other parameters are noted. The approximate inflation in mean absolute error due to estimating the regression coefficients is a function of the base sample size and number of predictors. (DWH)

Monte Carlo results were used to evaluate procedures for discriminating between groups. A multiple testing version of Hotelling's T-squared and the Bonferroni procedure were most powerful for detecting at least one true difference, depending on conditions examined. A multiple Bonferroni procedure was superior in power for detecting all true…

Describes the author's efforts to develop a means of teaching biology that facilitates learning and improves students' self-attitudes. Results indicate that students are more academically successful when the instructional materials complement the students' style of thinking. (Author/MA)

Evaluations involving nonrandom assignment to treatment or control groups are vulnerable to an accidental or intentional confounding of a selection effect with the treatment effect. Two techniques, discriminant analysis and base expectancy analysis, permit separate estimation of the selection and treatment effects in the final results. (Author/CTM)
