Summary

This book serves as an ideal textbook and reference book for students and researchers in the behavioral sciences and education. It includes a diagram of each design that illustrates how subjects are assigned to treatments, the use of boldface type to emphasize new terms, summaries of the advantages and disadvantages of the designs, and a plethora of review exercises. The most obvious change in the fourth edition is the sequence of the chapters. Other changes include an expanded coverage of exploratory data analysis, measures of practical significance, determination of sample size and power, and one degree-of-freedom measures. The latest advances in the rapidly expanding area of multiple comparisons are described in Chapter 5 along with recommendations for their use. Improved procedures for testing the tenability of assumptions in analysis of variance are described in Chapters 3, 4, and 8. This edition demonstrates the flexibility of the cell means model for analyzing data with missing observations and missing cells.
