This textbook provides a comprehensive, user-friendly guide to meta-analysis and how to conduct it, using open source software and based on examples commonly found in the field of psychology. Meta-analysis is a key tool used in systematic literature reviews to synthesize research findings across studies, but despite being relatively straightforward to perform, it remains underused by psychologists. In the first section the reader is introduced to key ideas that underlie meta-analysis and how it might be best employed. Following this the reader is guided through how to run a meta-analysis of correlational studies and experimental studies using the free and open statistical software JAMOVI. In the concluding section Professor Cooke considers common issues, key debates and examines the relative merits of different analyses and different software packages. It will provide a valuable new resource for postgraduate students and researchers in the behavioural and social sciences looking to enhance their methodological skills. weiterlesen
