Statistical Conclusion Validity of Early Intervention Research with Handicapped Children.
Ottenbacher, Kenneth J.
Exceptional Children, v55 n6 p534-40 Apr 1989
The study examining the validity of statistical conclusions of 49 early intervention studies found that 4 percent had adequate power to detect medium intervention effects and 18 percent to detect large intervention effects. Low statistical conclusion validity has practical consequences in program evaluation and cost-effectiveness determinations. (Author/DB)
