Logically consistent hypothesis-testing for factorial analysis of variance designs is proposed in the context of a hierarchical model. It is shown that all of the hypotheses associated with the traditional factorial model are conceptually independent and occupy the lowest levels of the hierarchy. (Author/JKS)

The results of an extensive analysis of the statistical methodology employed by researchers whose manuscripts were published in the first twelve volumes of the "Educational Administration Quarterly" are reported. (Author)

This volume contains the five major addresses and subsequent discussion from the Symposium on the General Linear Models Approach to the Analysis of Experimental Data in Educational Research, which was held in 1967 in Athens, Georgia. The symposium was designed to produce systematic information, including new methodology, for dissemination to the…

Although the evaluation of innovations in teacher training is often dependent on observational data, the problem of the reliability of the observations collected by a team of observers has often been treated in a superficial manner, partially because of the difficulties of maintaining an observer team intact over an extended period of time and of…

An error in the data analysis for a study reported in a 1988 paper by Kail is cited. The paper postulated a model that explained individual differences in the speed of processing on cognitive tasks. Reanalysis of the data suggested that support for the original conclusions is considerably weaker than reported. (LB)

This memorandum, part of a series, critically examines the fixed-effects analysis of variance procedure used in an intensive classroom study. The procedure, used by Gentile, Roden and Lein (Journal of Applied Behavioral Analysis, 1972, 5) for intensive studies of single subjects, is found inappropriate because the basic assumptions of an analysis…

The language skills category of objectives of the Appalachia Preschool Education Program as measured by the Illinois Test of Psycholinguistic Abilities (ITPA), is discussed. The point is made that one of the difficulties associated with evaluating language development is the loose fit between available theoretical and operational definitions of…

This paper examines the development and evaluation of criterion-referenced measures, and elaborates on the distinction between them and norm-referenced measures. The concept of sensitivity is introduced as an appropriate method for evaluating such measures, and a sensitivity index is proposed. The traditional model for the response of a subject to…

When two groups, initially dissimilar, undergo different treatments, can subsequent differences be partitioned in such a way that the difference between the two treatments is unbiased? This is the central problem of this paper, and it is confronted by the examination of two levels of information using a Follow Through Evaluation. The first…
