Wirt, Edgar – Journal of Experimental Education, 1987
In negotiating to obtain a sample of records from a computer file, it is important to be able to present a simple program that will produce a representative and valid sample. This article describes two procedures: (1) an interval selection method; and (2) a random numbers file. (JAZ)

Williams, Richard H.; Zimmerman, Donald W. – Journal of Experimental Education, 1984
This paper provides a list of 10 salient features of the standard error of measurement, contrasting it to the reliability coefficient. It is concluded that the standard error of measurement should be regarded as a primary characteristic of a mental test. (Author/DWH)

Williams, Richard H.; Zimmerman, Donald W. – Journal of Experimental Education, 1980
It is suggested that error of measurement cannot be routinely incorporated into the "error term" in statistical tests, and that the reliability of test scores does not have the simple relationship to statistical inference that one might expect. (Author/GK)

Hollingsworth, Holly – Journal of Experimental Education, 1980
A solution to some problems of maximized contrasts for analysis of variance situations when the cell sizes are unequal is offered. It is demonstrated that a contrast is maximized relative to the analysis used to compute the sum of squares between groups. Interpreting a maximum contrast is discussed. (Author/GK)

Schofield, Hilary L.; Start, K. B. – Journal of Experimental Education, 1979
Explanations are offered for observed discrepant and null findings in the area of predictive information about teacher effectiveness. It is argued that if tautologies are to be avoided, only product variables are appropriate criteria of success. Some recommendations regarding future research are offered. (Author/GSK)

Abrams, Allan S.; And Others – Journal of Experimental Education, 1979
Evaluation of large-scale programs is problematical because of inherent bias in assignment of treatment and control groups, resulting in serious regression artifacts even with the use of analysis of covariance designs. Nonuniformity of program implementation across sites and classrooms is also a problem. (Author/GSK)

Denton, Jon J.; McNamara, James F. – Journal of Experimental Education, 1979
Procedures from educational policy research were used to produce three conceptual models for determining teacher effects in classrooms. The use of a system of equations, as developed for these models, shows promise for theory building in teacher education and instructional design. (Author/GSK)

Nelson, Larry R. – Journal of Experimental Education, 1979
The authors state that multiple regression is a powerful method of statistical analysis, provides a strength of relationship index, and should replace analysis of variance (ANOVA) in educational research. They also discuss the coding of categorical variables and available computer programs for multiple regression. (Author/MH)

Daniel, Larry G. – Journal of Experimental Education, 1997
Gives an overview of three of the myths that F. N. Kerlinger (1959, 1960) identified as pervading educational research. Explores the myths of methods, practicality, and statistics, and analyzes the degree to which they have been overcome or still exist. (SLD)

Huck, Schuyler W. – Journal of Experimental Education, 1991
This poem, with stanzas in limerick form, refers humorously to the many threats to validity posed by problems in research design, including problems of sample selection, data collection, and data analysis. (SLD)

Zimmerman, Donald W.; And Others – Journal of Experimental Education, 1992
D. W. Zimmerman argues that the interpretation by J. D. Gibbons and S. Chakraborti of recent simulation results and their recommendations are misleading and suggests use of an alternate test when homogeneity of variance and normality are violated. Gibbons and Chakraborti review their differences with Zimmerman's position. (SLD)

Levin, Joel R.; And Others – Journal of Experimental Education, 1993
Journal editors respond to criticisms of reliance on statistical significance in research reporting. Joel R. Levin ("Journal of Educational Psychology") defends its use, whereas William D. Schafer ("Measurement and Evaluation in Counseling and Development") emphasizes the distinction between statistically significant and important. William Asher…
