A study that explored the relationship between the price of a book and the number of copies of a book sold found that raising prices by 1% reduced sales by 4% at BN.com, but reduced sales by only 0.5% at Amazon.com.
Such stories as these would not be possible to understand without statistics, the branch of mathematics that consists of methods of processing and analyzing data to better support rational decision-making processes. Using statistics to better understand the world means more than just producing a new set of numerical information—you must interpret the results by reflecting on the significance and the importance of the results to the decision-making process you face. Interpretation also means knowing when to ignore results, either because they are misleading, are produced by incorrect methods, or just restate the obvious, as this news story "reported" by the comedian David Letterman illustrates:
As newer technologies allow people to process and analyze ever-increasing amounts of data, statistics plays an increasingly important part of many decision-making processes today. Reading this chapter will help you understand the fundamentals of statistics and introduce you to concepts that are used throughout this book.
The five words population, sample, parameter, statistic (singular), and variable form the basic vocabulary of statistics. You cannot learn much about statistics unless you first learn the meanings of these five words.

Precept: Precepts are a good way to solidify your understanding of lecture material through practice questions and discussions in a small group. They are weekly, according to the schedule. We ask that you attend the precept section you are officially enrolled in. Office Hours: AI's office hours will be held in room 107 Sherrerd Hall. The instructor's office hours will held in room 205 Sherrerd Hall. Instructor: Mondays: 10:00am--11:00am and Wednesdays 4:30pm -- 5:30pm or by appointments Assistants in Instruction (AIs): Every day, there are office hours held by AIs and UCAs. Please see Canvas for details. AI's office hours are in room 007 Sherred Hall Text and Reference Books: The course textbook is not required for the class. However, it does contain many examples and practice questions and can serve as a good accompaniment to lecture and precept materials:
Syllabus: A first introduction to probability, statistics and machine learning. This course will provide background to understand andproduce rigorous statistical analysis including estimation, confidence intervals, hypothesis testing, regression, logistic regression and a brief introduction to machine learning. Applicability and limitations of these methods will be illustrated using a variety of modern real world data sets and manipulation of the statistical software R. Precepts are based on real data analysis using R.Course material will be covered thefollowing topics; some topics will be assigned as reading materials.
Attendance: We encourage active participation in lectures and precepts. These sessions cover many conceptual and practical issues and hone statistical thinking that cannot be learned from reading the text book and lecture notes alone. They will appear in the midterm and final exams. Homework: There will be 10 homeworks throughout the semester. Problems will be posted on Canvas. They will be due Wednesdays 11:30pm EDT/EST in the following week. You must show all your work, including your R code. You must submit a single pdf file containing answers to questions in the order presented. Missed homework will receive a grade of zero. All homeworks carry equal weight, except for the one on which you achieve the lowest score. The homework with the lowest score will carry 40% of its original weight. You are encouraged to work with other students in small groups on the homework problems, as some of the problems could be challenging. However, verbatim copying of homework is absolutely forbidden. Therefore each student must ultimately produce his or her own homework to be handed in and graded.
Exams: There will be a midterm that covers the first half of the course during mid-term week, and a cumulative final exam covering the entire course at the end of the semester. All exams are required and there will be no make-up exams. Missed exams will receive a grade of zero. All exams are open-book and open-notes. Laptops with wireless off and calculators may be used during exams.

Foundations of Statistics for Data Scientists: With R and Python is designed as a textbook for a one- or two-term introduction to mathematical statistics for students training to become data scientists. It is an in-depth presentation of the topics in statistical science with which any data scientist should be familiar, including probability distributions, descriptive and inferential statistical methods, and linear modeling. The book assumes knowledge of basic calculus, so the presentation can focus on "why it works" as well as "how to do it." Compared to traditional "mathematical statistics" textbooks, however, the book has less emphasis on probability theory and more emphasis on using software to implement statistical methods and to conduct simulations to illustrate key concepts. All statistical analyses in the book use R software, with an appendix showing the same analyses with Python.
The book also introduces modern topics that do not normally appear in mathematical statistics texts but are highly relevant for data scientists, such as Bayesian inference, generalized linear models for non-normal responses (e.g., logistic regression and Poisson loglinear models), and regularized model fitting. The nearly 500 exercises are grouped into "Data Analysis and Applications" and "Methods and Concepts." Appendices introduce R and Python and contain solutions for odd-numbered exercises. The book's website ( -aachen.de/) has expanded R, Python, and Matlab appendices and all data sets from the examples and exercises.
Lead author Gareth James is currently the Interim Dean of the Marshall School of Business at the University of South Carolina and is recognized as an expert on statistical methodology. The book, recommended by Quartz, Good Reads, Book Scrolling, and Wall Street Mojo, includes the following:
Wheelan is a senior lecturer and policy fellow at the Rockefeller Center at Dartmouth and a correspondent for The Economist. Wheelen states that he designed the book to apply statistical concepts to everyday life situations (e.g., how does polling work).
Two of the authors, Hastie and Tibshirani, co-authored An Introduction to Statistical Learning: with Applications in R. Lead author Trevor Hastie is a statistics professor at Stanford University. The book includes:
Wasserman is a professor in the Department of Statistics and the Machine Learning Department at Carnegie Mellon University. Recommended by both Book Scrolling and Book Authority, this book is an exhaustive view of statistical concepts. It is also the winner of the 2005 DeGroot prize (which is an honor awarded for outstanding statistical books).
Bulmer is a biostatistician and Fellow of the Royal Society of London, and an Emeritus Fellow of Wolfson College, Oxford. The original publication dates back to 1965 and remains popular. Good Reads indicates that this book remains distinctive in bridging statistical theory with practical application. The intent of this book is to enhance understanding of the concepts acquired in statistical courses.
Casella (1951-2012) was a distinguished professor in the Department of Statistics at the University of Florida. This highly recommended book breaks down the theories in statistics for increased comprehension. Intended for graduate students, it is noted as a handy reference book.
