The relative power of the Mann-Whitney statistic, the t-statistic, the median test, a test based on exceedances (A,B), and two special cases of (A,B) the Tukey quick test and the revised Tukey quick test, was investigated via a Monte Carlo experiment. These procedures were compared across four population probability models: uniform, beta, normal,…

Bounds for the tails of Dirichlet integrals are established by showing that each integral as a function of the limits is a Schur function. In particular, it is shown how these bounds apply to the simultaneous analysis of variance test and to the multinomial distribution. (Author)

The purpose of this study was to determine if answer sheet design, particularly a self-scoring answer sheet, was a differential variable of test anxiety. Data for the study was gathered from the administration of pre and post anxiety tests, given in conjunction with an in class psychology exam. Students in the control group used conventional IBM…

This note shows that, under conditions specified by Levin and Subkoviak (TM 503 420), it is not necessary to specify the reliabilities of observed scores when comparing completely randomized designs with randomized block designs. Certain errors in their illustrative example are also discussed. (Author/CTM)

Comments (TM 503 706) on an earlier article (TM 503 420) concerning the comparison of the completely randomized design and the randomized block design are acknowledged and appreciated. In addition, potentially misleading notions arising from these comments are addressed and clarified. (See also TM 503 708). (Author/CTM)

This note continues the discussion of earlier articles (TM 503 420, TM 503 706, and TM 503 707), comparing the completely randomized design with the randomized block design. (CTM)

The problems of two way analysis of variance designs with unequal and disproportionate cell sizes are discussed. A variety of solutions are discussed and a new solution is presented. (JKS)

Discusses criticisms of behavioral science research methodologies, and offers solutions which emphasize that it is only on the basis of theory that one can decide on an appropriate hypothesis to be tested, on a correct method of statistical analysis, and on whether the experimental results can be generalized to a population of interest. (Author/KS)

Describes how a combination of mapping and techniques can be used as a basis for measuring and analyzing student locational awareness of California. The case study analysis reveals that there was considerable variation in students' accuracy and precision in locating places. Includes tables and maps. (TRS)

The Welch-James procedure may be used to test hypothesis on means, when independent samples from populations with heterogenous variances are available. Summation formulas for the Welch-James procedure are presented for the 2x2 design. Matrix formulas that permit routine application of the procedure to crossed factorial designs are presented.…

This study applied nonparametric bootstrapping to test null hypotheses for selected statistics (KR-20, difficulty, and discrimination) derived from a student-made test. The test, administered to 21 students enrolled in a graduate-level educational assessment class, contained 42 items, 33 of which were analyzed. Random permutations of the data…

Large-scale testing programs often require multiple forms to maintain test security over time or to enable the measurement of change without repeating the identical questions. The comparability of scores across forms is consequential: Students are admitted to colleges based on their test scores, and the meaning of a given scale score one year …

Considered is the improvement of criterion-referenced measurement as applied to individual and group assessment of handicapped and normal children. (DB)

Using data collected from 30 high school districts within metropolitan New York, a direct positive relationship between the training of instructional staff at diversified, prestigious universities and per pupil expenditure was supported. On the basis of the small sample size this conclusion is considered exploratory. (LN)
