An undergraduate text for students of psychology and other behavioral sciences. In addition to being updated, the second edition has been reorganized to present experimental research first, followed by non-experimental research methods including quasi-experimental, correlational, and descriptive designs. It adds discussions of statistics and data structures to individual chapters in which specific research designs are introduced and integrates elements previously separated into an accompanying lab manual. The authors teach at the State U. of New York College at Brockport. Annotation ©2005 Book News, Inc., Portland, OR (booknews.com)
