Multiple Contrasts and Ordered Bonferroni Procedures.
Rosenthal, Robert; Rubin, Donald B.
Journal of Educational Psychology, v76 n6 p1028-34 Dec 1984
This article presents a system for avoiding Type I error increases when increasing the number of contrasts computed. Based on the Bonferroni inequality, the procedure corrects for the number of contrasts tested. Although conservative, the Bonferroni system is recommended for its flexibility, simplicity, and generality. (Author/BS)
