Conditional versus Unconditional Procedures for Sample-free Item Analysis
Two procedures for Rasch, sample-free, item calibration are reviewed and compared for accuracy. Andersen's (1972) theoretically' ideal "conditional" procedure is impractical for calibrating more than 10 or 15 items. A simplified alternative procedure for conditional estimation practical for 20 or 30 items which produces equivalent estimates is developed. When more than 30 items are analyzed rec...
متن کاملDifferential item functioning procedures for polytomous items when examinee sample sizes are small
As part of test score validity, differential item functioning (DIF) is a quantitative characteristic used to evaluate potential item bias. In applications where a small number of examinees take a test, statistical power of DIF detection methods may be affected. Researchers have proposed modifications to DIF detection methods to account for small focal group examinee sizes for the case when item...
متن کاملSELECTION PROCEDURES FOR THE t BEST POPULATIONS
SUMMARY Suppose one has k populations and wishes eventually to choose the "best" one. It is often desirable to use a multi-stage experiment, where at each stage, at least t (~l) populations are selected for further study. This paper is concerned with selecting at least t(~2) populations, presenting generalizations of two methods in existence for t = 1. One method has as its goal the selection o...
متن کاملSimple Procedures for Selecting the Best
In this paper we address the problem of nding the simulated system with the best (maximum or minimum) expected performance when the number of alternatives is nite, but large enough that ranking-and-selection procedures may require too much computation to be practical. Our approach is to use the data provided by the rst stage of sampling in a ranking-and-selection procedure to screen out alterna...
متن کاملBest practices for minimally invasive procedures.
Techniques and instrumentation for minimally invasive surgical procedures originated in gynecologic surgery, but the benefits of surgery with small incisions or no incisions at all have prompted the expansion of these techniques into numerous specialties. Technologies such as robotic assistance, single-incision laparoscopic surgery, natural orifice transluminal endoscopic surgery, and video-ass...
