Changes were studied that occur when the correlations between the six Medical College Admission Test scales and the scores on the Part I examination of the National Board of Medical Examiners are corrected for restriction of range. (MLW)

In this paper, a proposal is made by which a content validity coefficient can be calculated. An example of the use of the coefficient is given, demonstrating that different question combinations in a CSE biology examination in which a choice of questions was given gave different levels of content validity.

Three nonparametric alternatives to the parametric Bartlett test are presented for handling the K-sample equality of variance problem. The two-sample Siegel-Tukey test, Mood test, and Klotz test are extended to the multisample situation by Puri's methods. These K-sample scale tests are illustrated and compared. (Author/GDC)

Evaluations involving nonrandom assignment to treatment or control groups are vulnerable to an accidental or intentional confounding of a selection effect with the treatment effect. Two techniques, discriminant analysis and base expectancy analysis, permit separate estimation of the selection and treatment effects in the final results. (Author/CTM)

The vocabulary of sampling is examined in order to provide a clear understanding of basic sampling concepts. The basic vocabulary of sampling (population, probability sampling, precision and bias, stratification), the fundamental grammar of sampling (random sample), sample size and response rate, and cluster, multiphase, snowball, and panel…

Hoyt recommends the use of norm groups, to adjust student ratings of instruction. Prior methods of generating norm groups relied upon the use of volunteer subjects. Results of the present study indicate that volunteer teachers' student ratings were superior to nonvolunteer teachers' ratings. (Author/RD)

Logistic analysis of black journal articles suggests that black American publications have passed through cycles of intellectual interest." (Author/JM)

Examines children's readers to find out whether Riesman, Glazer, Denney, and William F. Whyte's descriptions of changes in the American character are represented in the models offered to school children. Compares the models used in the early McGuffey Readers with contemporary readers. (Editor/RK)

Intention was to see if tendencies toward political and cultural radicalism could be identified as two separate dimensions of radicalism among adolescents and to study family characteristics which might explain a tendency toward radicalism. (Author/RK)

Intends to identify some of the problems associated with evaluation of a province-wide program, to describe how these problems were dealt with in the particular case under review, and to suggest how evaluators and their clients might approach problems of a similar nature. (Author/RK)

Investigates the relationship between Rotter's (1966) Internality-Externality Scale and Kohlberg's (1971) Morality Scale. Specifically addresses the question of whether Rotter's internal individual will be functioning at a higher level of Kohlber's stages of morality than the external individual. (Author/RK)

Discusses the application of the Kolmogorov-Smirnov two-sample tests, as an alternative to the Chi-square test, for survey research problems in business education and includes a computer program written for the convenience of researchers. The two-sample test is recommended for differentiating independent distributions. (MF)

Sets out the rationale of the Assessment of Performance Unit, a development that represents part of the Department of Education and Science's demands for greater accountability by the educational service for the resources it consumes. (Editor/RK)

Methods used in an educational indicators pilot project studying the conditions in primary schools in the least developed countries are described. Sample surveys with 88.88% to 100% response rates were conducted in 14 countries. Recommendations are made for improving sampling techniques in underdeveloped countries. (SLD)

A study investigated the effectiveness of a weighting procedure for adjusting survey results to correct for nonresponse bias. Using data from a Cooperative Institutional Research Program followup survey, results indicate that the procedure is highly effective in univariate distributions; its effectiveness in adjusting correlation and regression…
