Wollack, James A.; Cohen, Allan S.; Serlin, Ronald C.
Applied Psychological Measurement, v25 n4 p385-404 Dec 2001
Developed a family wise approach for evaluating the significance of copying indices designed to hold the Type I error rate constant for each examinee. Examined the Type I error rate and power of two indices under a variety of copying situations. Results indicate the superiority of a family wise definition of Type I error rate over a pair-wise definition. Discusses conditions under which Type I error control is lost. (SLD)
