Adjustment of observed cell means in factor designs reduces the chance of misinterpreting the interaction effect. The process of adjusting cell means for lower-order effects in two- and three-factor designs is described. Identifying and testing interaction contrasts are covered, and examples from the counseling literature are presented.…

Intended for use on Conversational Monitor System (CMS), the Tukey FORTRAN program facilitates pairwise comparisons among means following a significant Fratio in an analysis of variance. Tukey's statistic can be obtained by entering information regarding the design and analysis of variance results. Two variations are also available. (Author/BS)

A program is described utilizing a microcomputer and tape drive with any contingency or chi-square table from 2x2 to 8x8. It requires only the entering of the number of rows and number of columns, plus one-time entry of cell frequencies. (Author/JKS)

Focuses on Binomial Effect Size Display (a concept helpful in interpreting size of an experimental effect). Suggests that both statistical significance and explained variance be reported in experimental research and that values for the latter concepts can be viewed with a more accurate perspective by using BESD. (Author/JN)

Describes when and how to carry out many of the most common statistical tests including mean, standard deviation, confidence limits, correlation, regression, t-test, Chi square test, and ANOVA. Uses Excel to perform these operations. (DDR)

In this paper we explore the consequences of particular stage linkage structures for the evolution of a population. We first argue the importance of mixed-sex pairs of subjects discussed a legal case, each pair seated first five feet of examples the implications of various stage connections for poulation movements. In discussing dynamic models,…

COMPENSTAT, a menu-driven statistical program for IBM-compatible microcomputers, has two distinct versions: instructional and computational. The instructional version can be used by instructors as a classroom resource, and the computational version is used directly by students to calculate answers to problems. The software package is primarily…

Presents the results of an experiment that examined the extent to which a single provocative incident can exacerbate negative feelings toward a group as a whole. After hearing an audiotaped interview where a Latvian student criticized U.S. college students, the U.S. students responded differently to slides showing Latvians. (MJP)

Examines unresolved problems and future prospects for research concerning school quality. Asserts that the proportion of variance among factors such as, school system, school type, grade levels, individual schools, and learning groups makes consideration of the schools as a homogenous whole doubtful. Includes numerous statistical tables and…

Presents the results of an experiment that evaluated the efficiency of analogy in the conceptual restructuring of a science topic. The experiment involved a fifth-grade class studying water and heat flow. Discovered that analogy can act as an effective trigger for restructuring knowledge. (MJP)
