Eysenck's PEN Inventory and Lanyon's Psychological Screening Inventory were given to groups of male and female American undergraduates from a state university. A factorial analysis of the intercorrelations showed that three major factors could account for the bulk of correlations among the nine differently labeled characteristics covered by the…

When total scores on the California Preschool Social Competency Scale (CPSCS) of disadvantaged children attending New York State experimental prekindergarten programs in 1975-76 were replaced by factor scores derived through principal component analysis, exposure time had no significant relationship to three components of the scale:…

The purpose of this paper is to examine the capabilities of various procedures for sorting dichotomously-scored items into unidimensional subjects. The procedures include: factor analysis, nonmetric multidimensional scaling, cluster analysis, and latent trait analysis. Both simulated and real data sets of known structure were used to evaluate the…

Two sets of administrators (principals and superintendents) were asked if selected inservice education programs were being implemented currently in the respondents' schools and school systems and, secondly, what their perceptions were of the need for selected inservice education programs in the next five years. The study requested responses of a…

Four criterion-referenced reliability coefficicents were compared to the Kuder-Richardson estimates and to each other. The Kuder-Richardson formulas 20 and 21, the Livingston, the Subkoviak and two Huynh coefficients were computed for a random sample of 33 criterion-referenced tests. The Subkoviak coefficient yielded the highest mean value;…

THIS EXPERIMENT SOUGHT TO DETERMINE WHETHER CONSISTENT DIMENSIONS OF JUDGMENTAL BEHAVIOR CONCERNING STATEMENTS PRESENTED IN A GIVEN MEDIUM WOULD BE IDENTIFIED WITH DIFFERENT MEASURING INSTRUMENTS, AND WHETHER THE DIMENSIONS COULD BE RELIABLY REPRODUCED IN THE DIFFERENT MEDIA. 768 SUBJECTS RESPONDED TO 1 OF 4 CONCEPTS PRESENTED THROUGH EITHER THE…

FROM INFORMATION GIVEN TO THE AMERICAN ASSOCIATION OF JUNIOR COLLEGES BY 581 COLLEGES, 36 VARIABLES WERE IDENTIFIED IN THE AREAS OF TYPE OF CONTROL, CURRICULAR EMPHASIS, FINANCIAL CHARACTERISTICS, AND MISCELLANEOUS CHARACTERISTICS. AFTER THE COMPUTATION OF INTERCORRELATIONS AMONG THESE VARIABLES, FACTORING OF THE RESULTANT CORRELATION MATRIX…
