In this volume, Larry Toothaker provides the procedures that will enable researchers to establish the significance of differences between two comparable groups. Issues addressed include: planned versus post-hoc comparisons; step-by-step versus simultaneous test procedures; types of error ra])G unequal sample sizes and variances; and interaction tests versus cell mean tests. Examples are used to illustrate major concepts.
Multiple Comparison Procedures
Many different multiple comparison procedures are available for the one-way ANOVA. Given that you are using a t statistic and have made a decision about control of error rate, the choice of MCP is largely a choice of the critical value and thus the theoretical distribution. Table 2.1 ...
