Techniques for detecting synergistic effects in analysis of variance designs are presented and discussed. These techniques make it possible to apply some kinds of theoretical insights to the data analysis phase of a study: either by seeking synergistic effects implied or predicted by theory, or by seeking evidence of synergies as alternative…

Researchers have long been aware that "pretest sensitization" is a potential threat to the external validity of experimental studies. Only recently, however, has it been suggested that "posttest sensitization" might also limit the generalizability of results. This latter phenomenon would exist to the extent that the effects of…

The author reviews research which examines a specific aspect of achievement arousal concerning the variable, "self-importance" of immediate activity. It also examines the relationship between "self-importance" and "future-importance"--that is, the extent to which possession of a certain personality attribute is believed necessary for achieving…

A statistical model for analysis of multiple time-series observation is briefly outlined. The model incorporates a change parameter corresponding to intervention or interruption of the dependent series. The additional time-series are included in the model as covariates. The practical application of the procedure is illustrated with traffic…

The purposes of this study were to examine strengths and weaknesses of research methods used in reports of follow-up studies in higher education and to develop a set of guidelines for conducting follow-up studies in higher education. A careful examination of the literature was conducted to identify follow-up studies in higher education and 47…

This study examines the fakability of the Edwards Personality Inventory (EPI). Results indicate that Edwards was not successful in his attempts to control for social desirability. (CK)

A study was made of the use of consumer credit by Home Demonstration Club (HDC) members in Blount County, Tennessee, as a basis for planning educational programs. Data were secured by group interviews from 237 Home Demonstration Club members representing 24 clubs. The data were classified according to the members use of consumer credit: those who…

This report outlines the requirements for a comprehensive, objective, and integrated guide to design of library physical facilities. It then presents a research plan directed at development of three products: (1) an authoritative catalog of the present knowledge of library functions, elements, and techniques of design as they relate to library…

Trend analysis is explained in nontechnical language with examples given for both parametric and nonparametric situations. Similarities and differences between parametric and nonparametric trend analyses are conveniently charted. Practical research applications for Directors of Testing and Directors of Institutional Research are stressed. A linear…

Argues that systematic empirical assessment of organizational development (OD) interventions is important and can have benefits both for subject organizations and organizational researchers. Discusses suggested criteria for effective assessment of OD interventions. (For availability see EA 507 198.) (JG)

It is demonstrated here that standardized regression coefficients greater than one can legitimately occur. Furthermore, the relationship between the occurrence of such coefficients and the extent of multicollinearity present among the set of predictor variables in an equation is examined. Comments on the interpretation of these coefficients are…

A table of critical values is presented for use with Chacko's ordered alternatives test for the analysis of variance. (Author/JKS)

Procedures for carrying out a Shine Combined (repeated measures) Analysis of Variance (ANOVA) when there are unequal group sizes are described. (Author/JKS)

The conduct of multiple post hoc comparison procedures following an analysis of variance is discussed. Various procedures are contrasted in terms of appropriateness, power, and other features. Octhogonal and nonorthogonal comparisons are discussed. (JKS)

The basic assumption of Cooper's nonparametric test for trend (EJ 125 069) is questioned. It is contended that the proper assumption alters the distribution of the statistic and reduces its usefulness. (JKS)
