Using planned comparisons in management research: A case for the bonferroni procedure
介绍Bonferroni多重比较方法，论证其在管理研究中应更频繁和恰当使用，并与Scheffé事后比较方法对比，提供选择指南，涵盖单因素、多因素、协方差、重复测量及多元方差分析等设计。
This article describes the Bonferroni multiple-comparison procedure, and makes a case for researchers' more frequent and appropriate use of it. The procedure is discussed as a test that facilitates investigation of precise and powerful a priori multiple comparisons. Characteristics of the Bonferroni procedure are described in relation to the more familiar Scheffé post hoc multiple-comparison method, and a step-by-step guide for comparing and choosing between the two is provided. The Bonferroni procedure is discussed in detail in the context of one-factor analysis-of-variance designs. Application of the technique is then considered in the context of factorial designs, analyses of covariance, univariate repeated-measures analyses, multivariate analyses of variance, and recent sequential hypothesis-testing extensions. To aid the presentation, an example from the field of management is included.
