The Tenth Edition of the bestselling Investigating the Social World provides students with the critical skills necessary to evaluate research. Each chapter integrates instruction in the various core research methods with investigation of interesting aspects of our social world. The book has always sought to communicate the excitement of social research and the importance of carefully evaluating the methods we use in that research. This edition also includes updated coverage of each research method and features many new examples reflecting research on the key issues we have experienced since 2020: the COVID-19 pandemic, the rise of social justice movements, and threats to democracy. It also includes exercises based on the 2020 General Social Survey dataset. This textbook is also available in SAGE's Vantage platform for the first time.
