Porter, Kristin E. – Journal of Research on Educational Effectiveness, 2018
Researchers are often interested in testing the effectiveness of an intervention on multiple outcomes, for multiple subgroups, at multiple points in time, or across multiple treatment groups. The resulting multiplicity of statistical hypothesis tests can lead to spurious findings of effects. Multiple testing procedures (MTPs) are statistical…

Porter, Kristin E. – MDRC, 2016
In education research and in many other fields, researchers are often interested in testing the effectiveness of an intervention on multiple outcomes, for multiple subgroups, at multiple points in time, or across multiple treatment groups. The resulting multiplicity of statistical hypothesis tests can lead to spurious findings of effects. Multiple…

Allen, Laura K.; Snow, Erica L.; McNamara, Danielle S. – Grantee Submission, 2016
A commonly held belief among educators, researchers, and students is that high-quality texts are easier to read than low-quality texts, as they contain more engaging narrative and story-like elements. Interestingly, these assumptions have typically failed to be supported by the literature on writing. Previous research suggests that higher quality…

Nering, Michael L., Ed.; Ostini, Remo, Ed. – Routledge, Taylor & Francis Group, 2010
This comprehensive "Handbook" focuses on the most used polytomous item response theory (IRT) models. These models help us understand the interaction between examinees and test questions where the questions have various response categories. The book reviews all of the major models and includes discussions about how and where the models…

Flaherty, Brian P. – Developmental Psychology, 2008
Developmental research often involves studying change across 2 or more processes or constructs simultaneously. A natural question in this work is whether change in these 2 processes is related or independent. Associative latent transition analysis (ALTA) was designed to test hypotheses about the degree to which change in 2 discrete latent…

Seaman, Samuel; And Others – 1984
The probability of obtaining a significant statistic, using the parametric analysis of covariance (ANCOVA) and the rank transform ANCOVA, was estimated for three conditions defined in terms of conditional distributions for two groups. The distributions were both normal, both skewed in the same direction but to different degrees, or both skewed to…

Kerr, Michael; And Others – 1986
The Kaufman Assessment Battery for Children (K-ABC) is purported to be less culturally biased than other, traditional measures of intellectual ability. The present study was designed to investigate three specific research questions: (1) Are there overall performance differences between Native American and non-Native American children on the WISC-R…

Topping, K. J.; Samuels, J.; Paul, T. – British Educational Research Journal, 2008
To explore whether different balances of fiction/non-fiction reading and challenge might help explain differences in reading achievement between genders, data on 45,670 pupils who independently read over 3 million books were analysed. Moderate (rather than high or low) levels of challenge were positively associated with achievement gain, but…

Biester, Thomas W. – 1985
This paper presents results of a study examining the relationship between the American Board of Surgery's In-Training Examination and its Qualifying Examination. 1982 Test scores on both examinations of 764 candidates in their fifth year of training as Chief Residents were analyzed. Descriptive statistics, correlations, and standard errors were…

Holmes, Susan E. – 1986
This research, conducted for California State Department of Education, is one component of a feasibility study focusing on ways to make the testing process more efficient by application of multi-purpose tests (MPT). MPT are designed, administered and scored to serve more than one purpose and to consolidate and unify testing programs as a partial…

Sevier, Robert; And Others – Roeper Review, 1994
Thirty-five gifted elementary children were tested with the Wechsler Intelligence Scale for Children III (WISC-III) and results were compared to a previous administration of the WISC (Revised). Scores were significantly higher on all three WISC-R global scales and most subtest scaled scores. Correlation coefficients between the tests were…

Slate, John R.; Jones, Craig H. – Diagnostique, 1995
Comparison of Wechsler Intelligence Scale for Children (WISC)-Revised and WISC III IQs for 64 students with specific learning disabilities and 55 students with mental retardation (MR) found that correlations were lower than those reported in the WISC-III manual. Only Performance IQs for students with MR matched the correlations reported in the…

Hoedt, Kenneth C.; And Others – 1984
Using a Monte Carlo approach, comparison was made between traditional procedures and a multiple linear regression approach to test for differences between values of r sub 1 and r sub 2 when sample data were dependent and independent. For independent sample data, results from a z-test were compared to results from using multiple linear regression.…

Angoff, William H. – 1985
This paper points out that there are certain generalizations about directions for guessing and methods of scoring that require that data be derived from random groups design. It supports the viewpoint that it is neither sufficient nor appropriate to make such generalizations on the basis of an analysis of scores obtained from the answer sheets of…
