One of the pathways by which the scientific community confirms the validity of a new scientific discovery is by repeating the research that produced it. When a scientific effort fails to independently confirm the computations or results of a previous study, some fear that it may be a symptom of a lack of rigor in science, while others argue that such an observed inconsistency can be an important precursor to new discovery. Concerns about reproducibility and replicability have been expressed in both scientific and popular media. As these concerns came to light, Congress requested that the National Academies of Sciences, Engineering, and Medicine conduct a study to assess the extent of issues related to reproducibility and replicability and to offer recommendations for improving rigor and transparency in scientific research. Reproducibility and Replicability in Science defines reproducibility and replicability and examines the factors that may lead to non-reproducibility and non-replicability in research. Unlike the typical expectation of reproducibility between two computations, expectations about replicability are more nuanced, and in some cases a lack of replicability can aid the process of scientific discovery. This report provides recommendations to researchers, academic institutions, journals, and funders on steps they can take to improve reproducibility and replicability in science.

Covering print, photography, film, radio, television, and new media, this textbook instructs readers on how to take a critical approach to media and interpret the information overload that is disseminated via mass communication. This fourth edition of Keys to Interpreting Media Messages supplies a critical and qualitative approach to media literacy analysis. Now updated with conceptual changes, current examples, updated references, and coverage of new developments in media— particularly in digital, interactive forms—this book addresses all forms of information disseminated via mass communication. Organized into three sections, the book first presents a theoretical framework for the critical analysis of media text that covers the definition of media literacy as well as fundamental principles and concepts. Part II focuses on the application of this methodological framework to the analysis of advertising, journalism, American political communications, and interactive media. Part III considers specific mass media issues, such as violence in the media, media and children, and global communications, and discusses outcomes of having a media-literate population.

Increased attention is being paid to the need for statistically educated citizens: statistics is now included in the K-12 mathematics curriculum, increasing numbers of students are taking courses in high school, and introductory statistics courses are required in college. However, increasing the amount of instruction is not sufficient to prepare statistically literate citizens. A major change is needed in how statistics is taught. To bring about this change, three dimensions of teacher knowledge need to be addressed: their knowledge of statistical content, their pedagogical knowledge, and their statistical-pedagogical knowledge, i.e., their specific knowledge about how to teach statistics. This book is written for mathematics and statistics educators and researchers. It summarizes the research and highlights the important concepts for teachers to emphasize, and shows the interrelationships among concepts. It makes specific suggestions regarding how to build classroom activities, integrate technological tools, and assess students’ learning. This is a unique book. While providing a wealth of examples through lessons and data sets, it is also the best attempt by members of our profession to integrate suggestions from research findings with statistics concepts and pedagogy. The book’s message about the importance of listening to research is loud and clear, as is its message about alternative ways of teaching statistics. This book will impact instructors, giving them pause to consider: "Is what I’m doing now really the best thing for my students? What could I do better?" J. Michael Shaughnessy, Professor, Dept of Mathematical Sciences, Portland State University, USA This is a much-needed text for linking research and practice in teaching statistics. The authors have provided a comprehensive overview of the current state-of-the-art in statistics education research. The insights they have gleaned from the literature should be tremendously helpful for those involved in teaching and researching introductory courses. Randall E. Groth, Assistant Professor of Mathematics Education, Salisbury University, USA

This fifth edition of Research Methods and Statistics in Psychology has been revised and updated, providing students with the most readable and comprehensive survey of research methods, statistical concepts and procedures in psychology today. The book assumes no prior knowledge, taking you through every stage of your research project in manageable steps. Advice on planning and conducting studies, analysing data and writing up practical reports is given, and examples provided, as well as advice on how to report results in conventional (APA) style. Unlike other introductory texts, there is discussion of commonly misunderstood concepts such as ecological validity, the null hypothesis and the role of cross-cultural psychology studies. Qualitative research is included in the central research methods chapters as well as being highlighted in specialist chapters which cover content analysis, grounded theory, interpretative phenomenological analysis (IPA), narrative analysis, discourse analysis and how to tackle a qualitative research project. The book provides clear coverage of statistical procedures, and includes everything needed at undergraduate level from nominal level tests to multi-factorial ANOVA designs, multiple regression and log linear analysis. In addition, the book provides detailed and illustrated SPSS instructions (updated to version 16) for all statistical procedures, including data entry and interpreting output, thus eliminating the need for an extra SPSS textbook. Each chapter contains a glossary, key terms and newly integrated exercises, ensuring that key concepts are understood. A companion website (www.routledge.com/cw/coolican) provides additional exercises, revision flash cards, links to further reading and data for use with SPSS. The bestselling research methods text for almost two decades, Research Methods and Statistics in Psychology remains an invaluable resource for students of psychology throughout their studies.
