Criteria for prediction of multinomial responses are examined in terms of estimation bias. Logarithmic penalty and least squares are quite similar in behavior but quite different from maximum probability. The differences ultimately reflect deficiencies in the behavior of the criterion of maximum probability.

A crucial question in any study is how representative the sample is of the population being studied at the time of the interview. This is of particular concern when the study is based on a follow-up of a sample of respondents initially interviewed for other purposes. This study evaluated the representativeness of a sample of elderly female…

To assess the effect on discriminant analysis in terms of correct classification into two groups, the following parameters were systematically altered using Monte Carlo techniques: sample sizes; proportions of one group to the other; number of independent variables; and covariance matrices. The pairing of the off diagonals (or covariances) with…

A new approach is presented for the meta-analysis of data from pre-test/post-test designs. With this approach, data from studies using different designs may be compared directly and studies without control groups need not be omitted. The approach is based on a "standardized mean-change" measure, computed for each sample within a study,…

This handbook is intended to help educational evaluators use still photography in designing, conducting, and reporting evaluations of educational programs. It describes techniques for using a visual documentary approach to program evaluation that features data collected with a camera. The emphasis is on the aspects of educational evaluation…

The perceptions of teachers in black high schools as compared to teachers in white high schools and the perceptions of black teachers in black high schools as compared to white teachers in black high schools were examined using five variables. (Author/RK)

The position of the "purists" who insist on limiting data to ordinal analysis is contrasted with the "pragmatists" who treat data as interval. (Author)

The present research is an attempt to isolate and study certain personnel behavior and their relationship with demographic variables, by combining the logic of subgrouping analysis with the managerial styles manifested in an inbasket exercise. (Author/RK)

The aim of this article is to give some basic information on the IEA survey in science, reading comprehension and literature so that the scene is set for the reader to understand the terminology and procedures reported in the articles which follow. (Author)

Article investigated Nuffield curriculum reforms, their effect on science learning and the overall success of these reforms. (Author/RK)

This article attempted to determine the opinions of experienced teachers enrolled in selected courses at East Texas State University regarding the objectives of American education. (Author/RK)

A Bayesian Model II approach to the estimation of proportions in m groups is extended to obtain posterior marginal distributions for the proportions. The approach is extended to allow greater use of prior information than previously and the specification of this prior information is discussed. (Author/RC)

Four different extensions to McNemar's problem concerning the hypothesis of equal probabilities for the unlike pairs of correlated binary variables are considered, each for testing simultaneous equality of proportions of unlike pairs in c independent populations of correlated binary variables, but each under different assumptions and/or additional…

Monte Carlo methods were used to investigate the robustness of techniques used in judging the magnitude of a sample correlation coefficient when observations are correlated. Empirical distributions of r, t, and Fisher's z were generated. A technique for controlling error rates in certain situations is suggested. (Author/BJG)

Major interest is the derivation of a mathematical formulation and a demonstration of the effects of pooling two subgroups on the total group correlation coefficient, and additionally, a procedure to guide the decision concerning the pooling of data for the purpose of calculating a single correlation coefficient.
