Overview

Gravetter/Forzano's RESEARCH METHODS FOR THE BEHAVIORAL SCIENCES, 7th Edition, provides an explanation of experimental and non-experimental methods that are accessible, engaging and current. The text leads students through the research process from start to finish, including tips and strategies for generating research ideas and hypotheses, selecting measures and participants and designing research. This step-by-step approach emphasizes the decisions researchers must make at each stage of the process. The "lecture in a book" style emphasizes clear, thorough explanations. Updates concisely teach students to carry out the right analysis for their research design in R, SPSS or by hand. The text has been updated to include recent research examples, while retaining its conversational style and accessible format.
