Dent, Clyde W.; Sussman, Steve Y.; Stacy, Alan W.
Evaluation Review, v21 n6 p698-712 Dec 1997
Differences between means, variance, and correlation parameter estimates from a full school sample and samples restricted by parental consent were studied with 1,609 students at continuation high schools and 1,192 at traditional high schools. Sample bias due to consent policies may not be a substantive problem, especially if a telephone consent procedure is implemented. (SLD)
