Many of the measurement aspects of nursing research have been governed by rules regarding the minimum values of certain summary indexes (such as Cronbach's coefficient alpha and Cohen's kappa), the required numbers of subjects per item for factor analyses, and the like. In this article a case is made for violating these rules whenever the circumstances warrant such violations. ©1995 John Wiley & Sons, Inc.
