Moneyball: The Art of Winning an Unfair Game Review

Lewis, who previously wrote some of the best books on Wall Street's go-go '80s (Liar's Poker) and Silicon Valley's go-go '90s (The New New Thing), here turns his attention to professional baseball. Now, I should preface this by saying that I used to love baseball and these days it doesn't interest me much at all. There was a time when I was a total stats geek, I bought all the Bill James abstracts, played tabletop games, etc., but a combination of playing in college and the escalating money completely turned me off to the game. I knew this was supposed to be a good book but had no intention of reading it until Nick Hornby's rave review in his column in The Believer. I figured if one of my favorite British novelists liked the book, there must be something to it. I picked it up and within ten pages I was totally hooked.
The basis for the book is the question of how the Oakland A's, one of baseball's poorest teams as measured by payroll, managed to win so many games in the first few years of the new millennium. Lewis's potentially boring answer revolves around inefficiencies in the market for players, but he weaves this story around the A's General Manager, Billy Beane. Now, if you have some axe to grind with Beane, you might as well not read the book, 'cause Lewis tends to be rather fawning in many places. Still, Beane's own background and mediocre career form the perfect framework upon which to build this story about evaluating baseball talent. Beane was a hugely athletic, "can't miss" prospect, who turned down a joint football/baseball scholarship from Stanford to sign with the New York Mets out of high school. His pro career turned out to be utterly undistinguished, and this disconnect is what drove him to seek new methods of scouting and evaluating baseball talent. It also helped matters that the A's new owners refused to spend any excess money, and demanded that the team be treated as a business. Beane jettisoned conventional scouting wisdom (and to a certain extent, methods), to focus on statistical indicators not widely followed inside baseball. Here, the book takes a detour into the realm of "sabremetrics" (the statistical analysis of baseball), and various attempts to arrive at more meaningful ways to calculating a player's offensive value.
The result of developing a criteria of player valuation that was radically at odds with the prevailing wisdom of the market was that Beane was able to get the players he liked for very cheap. The rest of the book is devoted to detailing this process. Chapter 5 is probably the best, detailing how the A's orchestrated the 2002 amateur draft so that they got an inordinate amount of players they coveted for below market value. Chapters 6 and 7 discuss the loss of their three star players after the 2001 season and how managed to compensate for this. To show the Beane methodology in action during the season, the reader is taken inside several trades and roster moves. This includes a chapter on the mid-season trade for relief pitcher Ricardo Rincon, bracketed by chapters detailing Beane's pursuit of certain players who were not considered major-league material (Scott Hatteberg and Chad Bradford). The book ends on a valedictory note, as the A's set a record by winning 20 games in a row and other teams start to buy in to their methods.
It should be noted that the book is far from perfect. Lewis has an unfortunately tendency for repetition when it comes to important points and themes, hammering them home, again and again. And although he does point out many of Beane's logical inconsistencies and emotional flaws, Lewis does often come across as more of an enamored fan than a strict journalist. Some critics feel that the A's success detailed in the book was based on several star players obtained the old-fashioned way, thus disproving the whole premise. However, it has to be understood that the practices detailed in the book can't really be proven to work one way or another for another decade or so. Still the insights into challenging conventional thinking and searching for alternative data or data patterns will likely appeal to readers of Lewis' other works and are applicable far beyond baseball. And while the jury is still out, several other teams have since hired general managers with the same basic philosophy as Beane. Ultimately, it's an interesting story, and one that Lewis tells very well -- even for non baseball fans.

Statistics for the Behavioral Sciences Review

When I had to take statistics as an undergraduate psychology student, I struggled to get through the course and was fortunate to get a "C". As a doctoral student in clinical psychology, I had to once again take statistics and I had nightmares of once again trying to get a passing grade. However, I am happy to say that I passed statistics and actually got an "A". I firmly believe it is due in large part to this textbook by Gravetter & Wallnau.
The tone of the textbook is relaxed and conversational. The authors definitely believe in keeping their explanations of sometimes complex statistical concepts as simple as possible. The book is filled with figures, step-by-step explanations of how to solve problems, and learning checks within each chapter to test your understanding of the material. After completing each chapter, I felt that I was more than prepared to tackle the problems at the end of each chapter.
If you have to take statistics, you might as well try to make the experience as pleasant as possible. And this book will definitely help you maintain your sanity, while actually teaching you about statistics.

Statistics for the Behavioral Sciences Overview

By far the best-selling introduction to statistics for students in the behavioral and social sciences, this text continues to offer straightforward instruction, accuracy, built-in learning aids, and real-world examples. The goal of STATISTICS FOR THE BEHAVIORAL SCIENCES, 8th Edition is to not only teach the methods of statistics, but also to convey the basic principles of objectivity and logic that are essential for science and valuable in everyday life. Authors Frederick Gravetter and Larry Wallnau help students understand statistical procedures through a conceptual context that explains why the procedures were developed and when they should be used. Students have numerous opportunities to practice statistical techniques through Learning Checks, examples, step-by-step Demonstrations, and problems. A strong ancillary package includes PowerLecture', which contains lecture slides, JoinIn' Student Response System content, and a computerized test bank; Enhanced WebAssign, a complete and easy-to-use homework management system; WebTutor'; an Instructor's Manual/TestBank, plus other online and print resources.

Cartoon Guide to Statistics Review

This book is exceptional in its ability to communicate difficult concepts in a light and entertaining manner. It seems to me that those who gave this book low ratings seem to think that the book should have magically imparted its knowledge upon them with no effort on their part.
Indeed, although Gonick presents the details via cartoons, that does not change the fact that "Sigma" is still "Sigma", and if you don't understand exactly what "Sigma" represents before moving on to the next concept, then you will not understand the subsequent lessons.
ie. Just because cartoons tell the tale, it doesn't mean that you will breeze through this book as you might a comic book. The individual concepts must be read and reread and perhaps even contemplated in order to truly understand each one before moving on to the next concept. If you do not do this, then, of course, nothing will make sense.
This is a book of statistics, not miracles...thus work will still be necessary in order to absorb the basic concepts within it.
Nevertheless, this book is far clearer and much more fun to read than any other stat book I've opened before. Very highly recommended.

Cartoon Guide to Statistics Overview

If you have ever looked for P-values by shopping at P mart, tried to watch the Bernoulli Trails on "People's Court," or think that the standard deviation is a criminal offense in six states, then you need The Cartoon Guide to Statistics to put you on the road to statistical literacy.
The Cartoon Guide to Statistics covers all the central ideas of modern statistics: the summary and display of data, probability in gambling and medicine, random variables, Bernoulli Trails, the Central Limit Theorem, hypothesis testing, confidence interval estimation, and much more-all explained in simple, clear, and yes, funny illustrations. Never again will you order the Poisson Distribution in a French restaurant!

The Basic Practice of Statistics: w/Student CD Review

Have to have this text for an online college statistics course I am taking. Text is well written. It presents the concepts in a clear and through fashion making it easy to learn the material. Would recommend it even if you are not taking a course and just wanted to teach yourself a basic grasp of statistics. With this text you can do it.

The Basic Practice of Statistics: w/Student CD Overview

The Basic Practice of Statistics has become a bestselling textbook by focusing on how statistics are gathered, analyzed, and applied to real problems and situations—and by confronting student anxieties about the course's relevance and difficulties head on. With David Moore's pioneering "data analysis" approach (emphasizing statistical thinking over computation), engaging narrative and case studies, current problems and exercises, and an accessible level of mathematics, there is no more effective textbook for showing students what working statisticians do and what accurate interpretations of data can reveal about the world we live in. In the new edition, you will once again see how everything fits together. As always, Moore's text offers balanced content, beginning with data analysis, then covering probability and inference in the context of statistics as a whole. It provides a wealth of opportunities for students to work with data from a wide range of disciplines and real-world settings, emphasizing the big ideas of statistics in the context of learning specific skills used by professional statisticians. Thoroughly updated throughout, the new edition offers new content, features, cases, data sources, and exercises, plus new media support for instructors and students—including the latest version of the widely-adopted StatsPortal. The full picture of the contemporary practice of statistics has never been so captivatingly presented to an uninitiated audience.

Epidemiology: with STUDENT CONSULT Online Access (Gordis, Epidemiology) Review

I agree with most of the other reviews here and also think this is a good introductory text. If you can get past the bad jokes and frequent references to Christianity, its clearly written and has good examples. However, this 4th edition is a classic example of an author repackaging an old textbook as a new edition and trying to make money off of it. Gordis claims that the 4th edition has many changes, but in reality the chapters are the same and only a few less significant references have been updated. My advice is to save your money and buy the third edition - just as good and much cheaper.

Elementary Statistics (11th Edition) Review

Our department has used Triola's statistics book for our large,
multi-section baby stats course for at least the past six years, and
it was through simple inertia that we adopted the 11th edition. Using
the earlier editions, I had almost begun to like Triola's
follow-the-recipe approach, and was able to make the course useful to
some of our students.
The 11th edition, however, is far worse than anything that came
before. The publishers have made numerous changes to format, style,
and content, and not one of them is for the better.
Format: The new edition has more clutter than ever in the margins.
Just about every page contains a distracting and usually irrelevant
sidebar, and color photographs (likewise irrelevant) push their way
into the text everywhere, as if the deisgners were trying to show off
their collection of pictures and their ability to flow text around
them. The actual text, when you can find it amid this clamoring
circus of marginal distractions, is marred by too-frequent changes in
background color and font size. It's difficult to read, and it's
difficult to orient oneself in the text, because the designers, while
splashing color and font changes all over the place, somehow managed
to make the chapter and section headings disappear. Just try to find
the beginning of Section 4-4. The decision to use a
proportional-space font in the tables of numbers on the Formulas and
Tables card suggests that the designer has never done any work with
tables of numbers.
Style: It's clear from the writing style that Dr. Triola is no longer
involved in the manufacture of the product that bears his name. (Or
else he had a very good copy editor in the earlier editions, who is
gone now.) A few paragraphs survive from the earlier editions, but
those that have been altered or inserted were written by someone
without the original author's grasp of English grammar. The new
author is also less careful about precise mathematical phrasing, and
is rather careless about things like referring to the probability of
an event that has already happened or the probability that a parameter
has a certain value. Many of the exercises now include a "tag-line"
question that is probably meant to help the students interpret the
results. A few of these questions are useful, but far more of them
require the student to speculate on or make judgments about subjects
with which he is almost certainly unfamiliar. In any case, they are
annoying, both to the student and to the instructor who must keep
repeating "Don't worry about that last part."
Content: How is it that later editions of the same book contain more
errors than earlier ones? Here are a few particularly nasty mistakes
that have been allowed into (or created for) the 11th edition:
Page 148, Exercise 9. "When rolling a single die at the Venetian
Casino in Las Vegas, there are 6 chances in 36 that the outcome is a
7." Does no one proofread these exercises? (Or does the Venetian
Casino really use 36-sided dice?)
Page 168, Exercise 17. The table supplied with the exercise is
missing its column headers. Again, this should have been caught by a
proofreader.
Page 433. There is an error in the presentation of the main formula
to be used in this section. And it's not just a slip-up in the
narrative text: The formula presented in the highlighted box is
incorrect. This is inexcusable. How could the proofreader have
missed it?
Page 484, Exercise 25. The exercise describes an observational study,
and concludes with the question "Should marijuana use be of concern to
college students?" The answer provided in the back of the book
suggests that the study shows a causal relationship between marijuana
use and impaired mental ability. This is in direct contradiction to
the rule that is so emphatically stated on pages 19 and 20: causality
may not be inferred from an observational study. The original author
would not have allowed such a blatant error to find its way into the
"officially correct" answers.
On the Formulas and Tables card -- the one that students use as a
reference when they're doing problems and taking exams -- the formula
for the chi-square test statistic is incorrect. How, then, are we to
trust anything else on this card? Where was the proofreader?
It does appear that Addison-Wesley, in the custom of the modern
producer of textbooks, rushed this edition through the mill, in order
to have all those overpriced copies on college bookstore shelves by
the beginning of the fall semester. In doing so, they apparently
omitted to have the book proofread or to give much thought to how
thoroughly the new design would discourage anyone from actually
reading it. Of course, it's possible that there's something even more
meretricious going on, and the publisher inserted the errors (all new
to the 11th edition) on purpose, so that the 11th edition could more
quickly be made obsolete, and replaced by an even more overpriced 12th
edition. I wouldn't put it past them.

Elementary Statistics (11th Edition) Overview

Mario Triola's Elementary Statistics remains the market-leading introductory statistics textbook because it engages students with an abundance of real data in the examples, applications, and exercises. Statistics is all around us in our daily lives, and Triola is dedicated to finding new real-world examples and data sets for you to use in your classroom.

The Eleventh Edition contains more than 2000 exercises, 87% of which are new, and 82% of which use real data. It also contains hundreds of examples, 86% of which are new and 94% of which use real data. By analyzing real data, students are able to connect abstract concepts to the world at large. As a result, they gain conceptual understanding and learn to think statistically, using the same methods that professional statisticians employ.

This text comes packaged with a CD-ROM that includes data sets in various formats and other resources. Data sets and other resources for this book are also available at our website.

Essentials of Epidemiology in Public Health, Second Edition Review

This book is an excellent introduction to epidemiology. The authors present epidemiologic concepts in an easy-to-understand manner with interesting supportive examples from the fields of reproductive health and HIV epidemiology. In addition to the standard chapters on study design, bias, and confounding, the book also includes very good chapters on measurement error, causation, and screening, as well as tried-and-proven guidelines for a critical review of epidemiologic studies. This text should be very helpful to beginning masters and doctoral students in epidemiology and public health.

Essentials of Epidemiology in Public Health, Second Edition Overview

Successfully tested in the authors' courses at Boston University and Harvard University, this text combines theory and practice in presenting traditional and new epidemiologic concepts. Broad in scope, the text opens with five chapters covering the basic epidemiologic concepts and data sources. A major emphasis is placed on study design, with separate chapters devoted to each of the three main analytic designs: experimental, cohort, and case-control studies.Full chapters on bias, confounding, and random error, including the role of statistics in epidemiology, ensure that students are well-equipped with the necessary information to interpret the results of epidemiologic studies. An entire chapter is also devoted to the concept of effect measure modification, an often-neglected topic in introductory textbooks. Up-to-date examples from the epidemiologic literature on diseases of public health importance are provided throughout the book.The second edition has been thoroughly revised with up-to-date examples and data from epidemiologic literature and features over 100 new study questions.

The Little SAS Book: A Primer, Fourth Edition Review

I support a fairly large SAS community in the private sector. I always recommend this book, but it isn't for everyone. I always recommend the most current version too. Maybe those reviewing this text at such a low level expected more detailed coverage. If you are a documentation junkie with considerable IT background, then go to the SAS site and read the documentation or purchase the course notes. The Little SAS Book is a series of short articles that hit all topics for a new SAS user. Many new SAS users have limited computing skills, e.g., Word and Excel, and our plunging into advanced statistics courses. The book is written in a folksy kind of style which might turn off some readers. If you have strong IT skills and now supporting statisticians that know SAS, then this book will aid in the conversation.

The Little SAS Book: A Primer, Fourth Edition Overview

Now in its fourth edition, The Little SAS Book is a classic, helping many people learn SAS programming. The book's friendly, easy-to-read style gently introduces readers to the most commonly used features of the SAS language. Topics include basic SAS concepts such as the DATA and PROC steps, inputting data, modifying and combining data sets, summarizing data, producing reports, and debugging SAS programs. Each topic is presented in a self-contained two-page layout complete with examples and graphics. This clear and concise format enables new users to get up and running quickly, while the examples allow readers to type in the program and see it work!
New topics in the fourth edition include ODS Graphics for statistical procedures, PROC SGPLOT for graphics, creating new variables in PROC REPORT with a COMPUTE block, WHERE= data set option, SORTSEQ=LINGUISTIC option in PROC SORT, and more functions, including ANYALPHA, CAT, PROPCASE, and YRDIF.
