Larry E. Toothaker | Akateeminen Kirjakauppa

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 rate; unequal sample sizes and variances; and interaction tests versus cell mean tests. Examples are used to illustrate major concepts.
