This book examines contrast analysis, which permits asking more focused questions of data. Through simple computations, greater statistical power and clearer substantive interpretations are the result. This book makes it possible for non-mathematical data analysts to simply and efficiently address the focused questions posed by their theories, hypotheses and hunches.

Researchers, teachers of research methods and graduate students will be familiar with the principles and procedures of contrast analysis included here, but will also be presented for the first time with a series of newly developed concepts, measures, and indices that permit a more useful application of contrast analysis.
