Essentials of Behavioral Research: Methods and Data Analysis

The only comprehensive treatment of methods and data analysis, this classic advanced undergraduate/graduate text in research methods requires statistics as a prerequisite. The first half of the text concentrates on research methods and the second half introduces students to advanced statistical procedures.

Contrasts and Effect Sizes in Behavioral Research

Contrasts are statistical procedures for asking focused questions of data. Compared to diffuse or omnibus questions, focused questions are characterized by greater conceptual clarity and greater statistical power when examining those focused questions. If an effect truly exists, we are more likely to discover it and to believe it to be real when asking focused questions rather than omnibus ones. Researchers, teachers of research methods and graduate students will be familiar with the principles and procedures of contrast analysis, but will also be introduced to a series of newly developed concepts, measures, and indices that permit a wider and more useful application of contrast analysis. This volume takes on this new approach by introducing a family of correlational effect size estimates.
