Determining the Efficacy of Intervention: The Use of Effect Sizes for Data Analysis in Single-Subject Research
Journal of Experimental Education Vol. 65, No. 1 (1996) pp. 73–93
Presents use of the effect size as a descriptive statistic for single-subject research. Discusses the way in which effect sizes augment interpretation of results, and reviews four types of treatment effects with case studies. An appendix includes a...
Randomly Missing Data in Multiple Regression: An Empirical Comparison of Common Missing Data Treatments
An investigation of the effects of randomly missing data in two-predictor regression analyses is described. The differences in the effectiveness of five common treatments of missing data on estimates of R-squared values and each of the two...
Eastern Educational Research Association 1998 (1998)
In a Monte Carlo analysis of single-subject data, Type I and Type II error rates were compared for various statistical tests of the significance of treatment effects. Data for 5,000 subjects in each of 6 treatment effect size groups were computer...
Screening Items for Bias: An Empirical Comparison of the Performance of Three Indices in Small Samples of Examinees
A Monte Carlo study was conducted to compare the performance of three statistical indices of test item bias in small samples of examinees. The statistical indices compared were the Delta method, the Mantel-Haenszel (MH) method, and the...
An Empirical Investigation of Equating Stability in a Single and a Double Linkage Design with Small Sample Sizes Using Angoff Model IV
Empirical evidence is presented of the relative efficiency of two potential linkage plans to be used when equivalent test forms are being administered. Equating is a process by which scores on one form of a test are converted to scores on another...
Annual Meeting of the Florida Educational Research Association (FERA) 2002 (November 2002)

Quarterly Review of Distance Education Vol. 8, No. 2 (2007) pp. 109–125
This study describes an investigation of the intellectual property policies of a stratified random sample of public and private Carnegie Doctoral Research-Extensive Universities. University policies were examined to determine whether or not they...
Nearest Neighbors, Simple Strata, and Probabilistic Parameters: An Empirical Comparison of Methods for Item Exposure Control in CATs
Annual Meeting of the National Council on Measurement in Education (NCME) 2001 (April 2001)
Computerized adaptive tests (CATs) are efficient because of their optimal item selection procedures that target maximally informative items at each estimated ability level. However, operational administration of these optimal CATs results in a...
