The computation of F ratios from cell means and standard deviations is shown for a two-way analysis of variance. (JKS)

The validity of five methods of estimating the reliability of criterion-referenced tests was evaluated across nine conditions of variability among item means. The results were analyzed by analysis of variance, the Newman-Keuls test, and a nonparametric procedure. There was a tendency for all of the methods to be conservative. (Author/JKS)

The Bashaw and Anderson correction for replicated errors in correlation coefficients was applied to the principal components analysis. Notable changes were found in the components in terms of the loadings and subsequently in the percentage of variance accounted for. (Author/JKS)

Sociology students were administered two Thurstone-type attitude scales under two conditions (with or without a "cannot decide" option), and a measure of ambiguity tolerance. The "cannot decide" option was used by a slight majority of students when available, but usage was not related to ambiguity tolerance. (Author/JKS)

Computer assisted tailored testing was used in a study of 163 Civil Service examinees to assess examinee's affective response to the testing setting. Response was summarized as overwhelmingly positive. (Author/JKS)

Linkages between the abilities and personality domains are explicated from the results of a study, in which cross-domain correlations between 20 ability variables and 14 personality traits were obtained and factor analyzed from a sample of adolescent males. (Author/CTM)

Using a new A-B measure of psychotherapist effectiveness derived from the Strong Vocational Interest Blank, this study sought to determine whether psychiatrists could be differentiated from other medical specialists. They could not. (Author/JKS)

The concepts of elevation, scatter, and shape are investigated as parameters in assessing the similarity among profiles of individuals. A computational strategy for differentiating the independent contribution of each parameter to more global indices of resemblance is presented. (Author/JKS)

The concept of psychosocial competence, or psychological effectiveness is investigated via three studies on college and high school students. The Behavioral Attributes of Psychosocial Competence measure used in these studies were found to differentiate between students rated competent or not competent by external sources. (JKS)

Following Conger's revised definition of suppressor variables, the universe relationships among two predictors and a criterion is analyzed. A simple mapping of relationships, based on the correlation between two predictors and the ratio of their validities, is provided. The relation between suppressor and part correlation is also discussed.…

When multiple-choice tests are scored in the usual manner, giving each correct answer one point, information concerning response patterns is lost. A method for utilizing this information is suggested. An example is presented and compared with two conventional methods of scoring. (Author/JKS)

The effects of repeaters (testees included in both administrations of two forms of a test) on the test equating process are examined. It is shown that repeaters do effect test equating and tend to lower the cutoff point for passing the test. (JKS)

Procedures to estimate the magnitude of a treatment effect are examined for analysis of variance (ANOVA) designs which have repeated-measures. In particular, it is argued that the estimate of utility (strength of effect) for a within-subjects variable should be adjusted to reflect the underlying ANOVA model. (Author/JKS)

The Koppa coefficient is a measure of association between two variables which have been measured dichotomously. Significance tests for comparing Koppa coefficients from multiple samples are presented. (JKS)

The General Education Performance Index (GEPI) is a comparatively short test covering the same content as the General Educational Development Test (GED), which takes ten hours to administer. Correlations of the subtests of the GEPI with the GED ranged from .28 to .57. (JKS)
