Book Description
From Joshua Angrist, winner of the Nobel Prize in Economics, and Jörn-Steffen Pischke, an accessible and fun guide to the essential tools of econometric research Applied econometrics, known to aficionados as 'metrics, is the original data science. 'Metrics encompasses the statistical methods economists use to untangle cause and effect in human affairs. Through accessible discussion and with a dose of kung fu–themed humor, Mastering 'Metrics presents the essential tools of econometric research and demonstrates why econometrics is exciting and useful. The five most valuable econometric methods, or what the authors call the Furious Five—random assignment, regression, instrumental variables, regression discontinuity designs, and differences in differences—are illustrated through well-crafted real-world examples (vetted for awesomeness by Kung Fu Panda's Jade Palace). Does health insurance make you healthier? Randomized experiments provide answers. Are expensive private colleges and selective public high schools better than more pedestrian institutions? Regression analysis and a regression discontinuity design reveal the surprising truth. When private banks teeter, and depositors take their money and run, should central banks step in to save them? Differences-in-differences analysis of a Depression-era banking crisis offers a response. Could arresting O. J. Simpson have saved his ex-wife's life? Instrumental variables methods instruct law enforcement authorities in how best to respond to domestic abuse. Wielding econometric tools with skill and confidence, Mastering 'Metrics uses data and statistics to illuminate the path from cause to effect. Shows why econometrics is important Explains econometric research through humorous and accessible discussion Outlines empirical methods central to modern econometric practice Works through interesting and relevant real-world examples

Book Description
"Mastering Research Methodology: A Practical Guide" assists professionals, scholars, and students in attaining a comprehensive understanding of the art and science of research. This all-encompassing manual provides explicitand exhaustive guidance on a wide range of research methodologies, encompassing qualitative and quantitative approaches. The book commences by providing readers with an introduction to fundamental concepts, including the significance of ethical considerations, hypothesis formulation, and research design principles. The subsequent section explores distinct research methodologies, such as mixed-methods, experimental, survey, case study, and ethnographic approaches. Every chapter of the book offers precise instructions on how to execute these methods, beginning with data collection and concluding with analysis, thereby guaranteeing that readers are capable of effectively applying these techniques to their own projects. The practical orientation of "Mastering Research Methodology" is one of its defining characteristics. Practical advice, real-world illustrations, and case studies serve to reconcile the divide between theoretical concepts and their real-world implementation. This practical methodology enables readers to comprehend the intricacies of scientific inquiry, arrive at well-informed methodological decisions, and confront prevalent obstacles. The book places significant emphasis on the essential significance of data integrity and research ethics, in addition to methodological instruction. This resource offers approaches to guaranteeing the integrity of data, preserving openness, and adhering to ethical principles during the entirety of the research endeavour.

Book Description
A core statistics text that emphasizes logical inquiry, not math Basic Statistics for Social Research teaches core general statistical concepts and methods that all social science majors must master to understand (and do) social research. Its use of mathematics and theory are deliberately limited, as the authors focus on the use of concepts and tools of statistics in the analysis of social science data, rather than on the mathematical and computational aspects. Research questions and applications are taken from a wide variety of subfields in sociology, and each chapter is organized around one or more general ideas that are explained at its beginning and then applied in increasing detail in the body of the text. Each chapter contains instructive features to aid students in understanding and mastering the various statistical approaches presented in the book, including: Learning objectives Check quizzes after many sections and an answer key at the end of the chapter Summary Key terms End-of-chapter exercises SPSS exercises (in select chapters) Ancillary materials for both the student and the instructor are available and include a test bank for instructors and downloadable video tutorials for students.

Book Description
Statistics is the field of knowledge concerned with data collection, data analysis, and data interpretation and presentation. Methodology comprises the many and varied structured ways in which research is conducted answering the fundamental question: How does the researcher effectively gather information for particular purposes? Both are core topics underlying the discipline of psychology and the other social, behavioral, and health sciences. Moreover, a basic understanding of the language of statistics and research methods is required for any serious student, scientist, and practitioner in these fields. The APA Dictionary of Statistics and Research Methods is a focused reference resource that explores the lexicon of these two tightly interrelated areas. It provides Over 4,000 entries offering clear and authoritative definitions; Balanced coverage in such core areas as research planning and design, psychometrics, quantitative and qualitative measurements, and data analysis; Hundreds of incisive cross-references that deepen the user's understanding of related topics; More than 100 illustrations of some of the common and uncommon data display methods; A Quick Guide to Use that explains stylistic and formal features at a glance; and Appendixes listing common abbreviations and statistical symbols The largest scientific and professional organization of psychologists in the United States and the largest association of psychologists in the world the American Psychological Association proudly offers this reference as part of its critically acclaimed APA Dictionaries series.
