Correct simple formulas are provided for the value of phi needed to use the commonly available Pearson and Hartley power charts in determining the power of hypothesis tests involving simple degree-of-freedom comparisons in the fixed effects analysis of variance. (LMO)

A new approach to partialling components is used. Like conventional partialling, this approach orthogonalizes variables by partitioning the scores or observations. Unlike conventional partialling, it yields a common component and two unique components. (Author/GDC)

The extension of regression estimation and poststratification to factor analysis is considered. These methods may be used either to improve the efficiency of estimation or to adjust for the effects of nonrandom selection. The estimation procedure may be formulated in a LISTREL framework. (Author/LMO)

Under the assumption of normalcy, a formula is derived for the reliability of the maximum score. It is shown that the maximum score is more reliable than each of the single observations but less reliable than their composite score. (Author/LMO)

The compatibility of the polychotomous Rasch model with dichotomization of the response continuum is discussed. It is argued that in the case of graded responses, the response categories presented to the subject are essentially an arbitrary polychotomization of the response continuum. (Author/LMO)

The technique of generalizing sample results in a classification study to large subpopulations of unequal sizes was examined. The usual output from the discriminant analysis routine in the Statistical Package for the Social Sciences was extended to handle the present statistical problems. Advantages of the technique were discussed. (Author/DWH)

The minimum number of points required for continuous scaled variables before the Pearson product moment correlation coefficient (PPMCC) ceases to be an accurate estimate if their original correlation coefficient is five. Results also indicated that the PPMCC obtained by using transformed discrete ordinal-level variables tended to underestimate the…

A sampling subspace in hypothesis testing where Type II error is made for completely illogical reasons from the standpoint of probability is described. The case of unequal probabilities of populations or conditions is also considered. (Author/BS)

New tests for comparing the strength of association between a variable and each of two potential predictor variables are proposed and compared to an existing test in a simulation study. Recommendations for use are made. (Author/JKS)

Contrary to the findings of previous studies that foreign students at British Universities are less successful academically than British students, this study concludes that Norwegian students had a lower failure rate and compared favorably in examination performance with British students. The question of whether motivation explains this high…

Changes in the full scale reliability of the WISC-R were computed at three age levels when each subtest was omitted by itself. The same procedure was followed with those subtests which independently had the smallest effect in lowering full scale reliability. Cautions were noted concerning the exclusion of subtests. (Author)

A table shows the ranking of 64 psychology-related journals. They were rated separately by frequency of citation in introductory psychology textbooks, frequency of citation in journals, and a poll of graduate school chairmen. (ND)
