“This is the book that I plan to teach from next time I teach introductory statistics. As it is, I recommend it as a reference for students in more advanced classes such as Applied Regression and Causal Inference, if they want a clean refresher from first principles.”—Andrew Gelman, coauthor of Regression and Other Stories“This is without doubt the best book to get started with data analysis in the social sciences. Readers learn best practices in research design, measurement, data analysis, and data visualization, all in an approachable and engaging way. My students—all of them complete novices—were easily able to conduct their own analyses after working through this book.”—Simon Weschle, Syracuse University“I love this book. More importantly, my students love this book. Data Analysis for Social Science is the perfect introduction to causal inference, probability and statistics, and the open-source programming language R, for students without prior experience. With multiple exercises using R Markdown and a variety of datasets drawn from the research literature, Data Analysis for Social Science gives students a hands-on path to build their skills and confidence.”—Anna Harvey, New York University“Data Analysis for Social Science helped me teach introductory research methods at the right level for the types of students in my class. This book provides detailed explanations, step-by-step examples, and repetition to ensure complete beginners are not overwhelmed and slowly build confidence. I also use it as an optional text for higher-level courses because it clearly explains concepts even PhD students are often confused about. Furthermore, the instructor resources that come with it are the best I’ve seen provided with a textbook and made adopting the book much easier.”—Mark Richardson, Georgetown University“Data science from zero to sixty—gently, expertly, quickly.”—Gary King, Weatherhead University Professor, Harvard University“This book will transform the way we teach data science in the social sciences. Assuming zero background knowledge, it takes readers step-by-step through the most important concepts of data analysis and coding without sacrificing rigor. With clear explanations, beautiful visuals, and engaging examples, Data Analysis for Social Science is the obvious choice for any student looking to build their data science tool kit.”—Molly Roberts, University of California, San Diego“I highly recommend Data Analysis for Social Science! It is exceptionally well-written and cleverly organized. I particularly love its problem-solving approach and how it is intertwined with R code. While most textbooks teach statistics without offering students a clear motivation, this one teaches statistics as a way to solve real problems with real datasets. For example, if you want to estimate average causal effects with randomized experiments, then you must learn to compute the mean of a subset of the data. Or, if you want to understand the precision of your estimates, then you need to learn probability (but not beforehand!). I am using this book in my undergraduate courses with great satisfaction, and my students appreciate its easily understandable explanations.”—Guillermo Solovey, University of Buenos Aires“My favorite feature of Data Analysis for Social Science is that it puts causal inference first, before probability and statistical inference. I have found that this unconventional order is gentler and more engaging for complete beginners than the approach used in many other books. It also allows students with some prior knowledge of statistics to learn something new from the start.”—Max Goplerud, University of Pittsburgh“Data Analysis for Social Science is a great textbook for any undergraduate research methods course. I especially like that it teaches point estimates and uncertainty separately. In the past, when I taught these concepts together, I found students were overwhelmed. Breaking them up makes the statistics easier to understand. It’s a genius idea! I truly can’t recommend this book enough!”—Christopher Ojeda, University of California, Merced“I have been teaching statistics for twenty-five years and I have never seen a book this well done. Data Analysis for Social Science is such a perfect combination of what students need to know. The authors’ descriptions of the basic logic of causality, along with the many practical examples and visuals, are amazing features. Also, I have been resisting teaching intro students R because I am very watchful of overloading their bandwidth and I worry about killing their spirit with buggy code; I want them to love data analysis as much as I do! This book made me a convert. I am going to spend the time to learn R so that I can assign this book.”—Vanessa Baird, University of Colorado, Boulder“I have used Data Analysis for Social Science to teach required undergraduate courses with great success. Students liked the clear explanations and relevant real-world examples, and they even found coding in R fun! By the end, they walked away excited about how these skills opened up new career opportunities and helped them understand the research discussed in other classes.”—Alicia Cooperman, George Washington University“Looking to get started with data science, but scared it’d be too complicated? This book has you covered. Data Analysis for Social Science truly delivers what the title claims: friendly and practical. The focus is on experimental data and causal inference much more than on multiple regression analysis, reflecting recent developments in the social sciences. I don’t think I’ve seen a more accessible introduction to R and RStudio—cheat sheets included!”—Didier Ruedin, University of Neuchâtel“Following the step-by-step guidance provided in this book, I built my skills in R rather than another expensive proprietary software, allowing me to share my growing knowledge with my working-class, first-generation students. I am confident I can continue to independently develop these skills in ways that support both my teaching and research.”—Jamie D. Gravell, California State University, Stanislaus“At last, we have a truly modern introduction to social science statistics. The authors do not shy away from topics like causal inference, and they gently and seamlessly integrate instructions on how to use R. This textbook is a generous gift to both students and teachers.”—Valerio Baćak, School of Criminal Justice, Rutgers University, Newark“A very sensible and intuitive introduction to data science. Llaudet and Imai do an excellent job of explaining the why of data analysis along with the how. I would recommend this book to anyone looking for a nice primer on data science coupled with a good set of tools using the R software.”—Craig Depken, University of North Carolina, Charlotte
