This updated edition offers practical guidance for understanding and implementing APA Style Journal Article Reporting Standards (JARS) and Meta-Analysis Reporting Standards (MARS) for quantitative research.

These standards provide the essential information researchers need to report, including detailed accounts of the methods they followed, data results and analysis, interpretations of their findings, and implications for future research.

This revised edition reflects updates to the original JARS and the MARS that meet developing needs in the behavioral, social, educational, and medical sciences. Harris Cooper analyzes examples from APA journals, offering readers advice for implementing these revised standards in their own writing while also conforming with the APA Style guidelines in the seventh edition of the Publication Manual of the American Psychological Association.

Updated chapters offer more detailed guidelines for reporting statistical analyses and unique elements of different types of research, including replication studies, clinical trials, and observational studies. This book is essential reading for experienced and early career researchers alike, as well as undergraduate and graduate students in research methods classes.
