Multiple-hypothesis testing in the context of a correlation matrix is used to compare the statistical power of the original Bonferroni with six modified Bonferroni procedures that control the overall Type I error rate. Three definitions of statistical power are considered: (1) the ability to detect at least one true relationship; (2) the ability…

Three computer simulations were conducted to show that very high aggregate predictive validity coefficients can occur when the across-case variability in absolute score stability occurring in both the predictor and criterion matrices is quite small. In light of the increase in internal consistency reliability achieved by the method of aggregation…

Empirically determines if two approaches, i.e., individual predictor information versus group information, would yield different predictive results, and since the second approach involved the additional expense of grouping whether the prediction of criterion measures by individual data could be enhanced by the addition of group data.

Two previous reports have specified the empirical structure of patients' and therapists' experiences in psychotherapeutic sessions. The present report explores the structure of experience within the therapeutic dyad--conjoint experience. (Author/RC)

The author presents a method of producing a scatter diagram of data on two variables with Pearson product moment correlation of .50; he also provides a proof that the method will work for any number of data pairs. (SD)

This paper reviews investigations concerning the nature of suicide in adolescence, attempting where relevant to distinquish it from suicidal behavior in other age groups. (Author)

Two studies of correlates of student preference for a single sex or coeducational college reflect that few girls in the studies wish to be isolated at a girls college. (Author/KM)

A scale was developed to measure attitude toward school among elementary school pupils. Scores on the questionnaire were positively correlated with teacher ratings of school attitudes, non-verbal ability, standardized tests of school achievement and self-concept scores for a sample of fourth grade pupils. (Author)

The study investigated the capacity of the Sixteen Personality Factor Questionnaire (16PF) to discriminate between those who frequently recall dreams and those who do not. The results are interpreted as indicating that the frequent recaller experiences less and the infrequent recaller experiences more intrapsychic conflict. (Author)

The calculation of second-order results in the validity assessment of measures and some useful interpretation aids are presented. First-order and second-order results give different and informative pictures of data dynamics. Several aspects of good practice in interpretation of second-order results are presented using data from 487 subjects…

Over the last decade or so, researchers have started to describe some of the ways young children begin to acquire and apply certain gender-relevant concepts, constructs, and behaviors. Researchers are beginning to build developmental models detailing young children's acquisition of certain gender-typed behaviors and gender schema factors. The…

This paper considers three clinical judgment biases in clinical inference: (1) illusory correlation bias, the report by clinicians of a correlation between psychodiagnostic test signs and patient's symptoms which are not correlated or are correlated to a smaller degree than that reported; (2) labeling bias, the tendency of exposure to diagnositc…

This report provides preliminary technical information on a method for analyzing the factors involved in the closing of elementary schools. Included is a presentation of data and a brief discussion bearing on descriptive statistics, reliability, and validity. An intercorrelation matrix is also examined. The method employs 9 factors that have a…

The question of regression to the mean is discussed in the contexts of the Title I Evaluation and Reporting System (TIERS) and the Bilingual Education Evaluation System (BEES), both of which involve assessing the achievement growth of project students from pre- to post-test. The correction formula recommended for use with TIERS was designed to…

This paper details how memory protocols obtained in individual interviews may be translated to scores on several dimensions suggested by White. White's nine dimensions are: (1) extent, (2) precision, (3) internal consistency, (4) accord with reality, (5) variety of types of element, (6) variety of topics, (7) shape, (8) ratio of internal to…
