These updates would serve to ensure the connection between the learner and the material that is conducive to learning. Journalism, Media Studies & Communications. of Contents 1. Also, a reminder for reviewers to save their work as they complete this review would be helpful. David M. Diez, Mine etinkaya-Rundel, Christopher D. Barr . Some of these will continue to be useful over time, but others may be may have a shorter shelf life. The text covers all the core topics of statisticsdata, probability and statistical theories and tools. This book has both the standard selection of topics from an introductory statistics course along with several in-depth case studies and some extended topics. The authors present material from lots of different contexts and use multiple examples. The content is accurate in terms of calculations and conclusions and draws on information from many sources, including the U.S. Census Bureau to introduce topics and for homework sets. It is a pdf download rather than strictly online so the format is more classical textbook as would be experienced in a print version. The B&W textbook did not seem to pose any problems for me in terms of distortion, understanding images/charts, etc., in print. Notation is consistent and easy to follow throughout the text. Especially like homework problems clearly divided by concept. In the PDF of the book, these references are links that take you to the appropriate section. For instance, the text shows students how to calculate the variance and standard deviation of an observed variable's distribution, but does not give the actual formula. Most of the examples are general and not culturally related. Access even-numbered exercise solutions. I do like the case studies, videos, and slides. Ability to whitelist other teachers so they can immediately get full access to teacher resources on openintro.org. I do not see introductory statistics content ever becoming obsolete. Also, as fewer people do manual computations, interpretation of computer software output becomes increasingly important. These sections generally are all under ten page in total. Another example that would be easy to update and is unlikely to become non-relevant is email and amount of spam, used for numerous topics. I suspect these will prove quite helpful to students. 0% 0% found this document useful, Mark this document as useful. For example, income variations in two cities, ethnic distribution across the country, or synthesis of data from Africa. There are also short videos for 75% of the book sections that are easy to follow and a plus for students. Books; Study; Career; Life; . Reviewed by Robin Thomas, Professor, Miami University, Ohio on 8/21/16, The coverage of this text conforms to a solid standard (very classical) semester long introductory statistics course that begins with descriptive statistics, basic probability, and moves through the topics in frequentist inference including basic The organization/structure provides a smooth way for the contents to gradually progress in depth and breadth. Some of the content seems dated. Additionally, as research and analytical methods evolve, then so will the need to cover more non-traditional types of content i.e mixed methodologies, non parametric data sets, new technological research tools etc. Table. Then, the basics of both hypothesis tests and confidence intervals are covered in one chapter. Some more modern concepts, such as various effect size measures, are not covered well or at all (for example, eta squared in ANOVA). The book is very consistent from what I can see. All of the calculations covered in this book were performed by hand using the formulas. Better than most of the introductory book that I have used thus far (granted, my books were more geared towards engineers). Introductory statistics courses prepare students to think statistically but cover relatively few statistical methods. Building on the basic statistical thinking emphasized in an introductory course, a second course in statistics at the undergraduate level can explore a large number of statistical methods. I also appreciated that the authors use examples from the hard sciences, life sciences, and social sciences. Students can check their answers to the odd questions in the back of the book. One of the real strengths of the book is the many examples and datasets that it includes. Jargon is introduced adequately, though. It is certainly a fitting means of introducing all of these concepts to fledgling research students. The examples and exercises seem to be USA-centric (though I did spot one or two UK-based examples), but I do not think that it was being insensitive to any group. Tables and graphs are sensibly annotated and well organized. differential equations 4th edition solutions and answers quizlet calculus 4th edition . I was able to read the entire book in about a month by knocking out a couple of subsections per day. The text would not be found to be culturally insensitive in any way, as a large part of the investigations and questions are introspective of cultures and opinions. But, when you understand the strengthsand weaknesses of these tools, you can use them to learn about the world. Reviewed by Barbara Kraemer, Part-time faculty, De Paul University School of Public Service on 6/20/17, The texts includes basic topics for an introductory course in descriptive and inferential statistics. After much searching, I particularly like the scope and sequence of this textbook. The formatting and interface are clear and effective. The graphs and diagrams were also clear and provided information in a way that aided in understanding concepts. Part I makes key concepts in statistics readily clear. The text also provides enough context for students to understand the terminologies and definitions, especially this textbook provides plenty of tips for each concept and that is very helpful for students to understand the materials. Archive. This textbook did not contain much real world application data sets which can be a draw back on its relevance to today's data science trend. The text, though dense, is easy to read. The writing is clear, and numerous graphs and examples make concepts accessible to students. Covers all of the topics usually found in introductory statistics as well as some extra topics (notably: log transforming data, randomization tests, power calculation, multiple regression, logistic regression, and map data). 2017 Generation of Electrical Energy is written primarily for the undergraduate students of electrical engineering while also covering the syllabus of AMIE and act as a This topic is usually covered in the middle of a textbook. For example, when introducing the p-value, the authors used the definition "the probability of observing data at least as favorable to the alternative hypothesis as our current data set, if the null hypothesis is true."

The book started with several examples and case study to introduce types of variables, sampling designs and experimental designs (chapter 1). Well, this text provides a kinder and gentler introduction to data analysis and statistics. 191 and 268). For example: "Researchers perform an observational study when they collect data in a way that does not directly interfere with how the data arise" (p. 13). The textbook has been thoroughly vetted with an estimated 20,000 students using it annually. The topics are presented in a logical order with each major topics given a thorough treatment. Each chapter is separated into sections and subsections. read more. Notation, language, and approach are maintained throughout the chapters. 4th edition solutions and quizlet . I have seen other texts begin with correlation and regression prior to tests of means, etc., and wonder which approach is best. It should be pointed out that logistic regression is using a logistic function to model a binary dependent variable. There are labs and instructions for using SAS and R as well. I was concerned that it also might add to the difficulty of analyzing tables. Statistical methods, statistical inference and data analysis techniques do change much over time; therefore, I suspect the book will be relevant for years to come. Many OERs (and published textbooks) are difficult to convert from a typical 15-week semester to a 10-week term, but not this one! read more. The text, however, is not engaging and can be dry. The topics are not covered in great depth; however, as an introductory text, it is appropriate. Create a clear way to explain this multi-faceted topic and the world will beat a path to your door. The drawbacks of the textbook are: 1) it doesn't offer how to use of any computer software or graphing calculator to perform the calculations and analyses; 2) it didn't offer any real world data analysis examples. The authors make effective use of graphs both to illustrate the For a Statistics I course at most community colleges and some four year universities, this text thoroughly covers all necessary topics. Statistics is not a subject that becomes out of date, but in the last couple decades, more emphasis has been given to usage of computer technology and relevant data. Reviewed by Leanne Merrill, Assistant Professor, Western Oregon University on 6/14/21, This book has both the standard selection of topics from an introductory statistics course along with several in-depth case studies and some extended topics. However, after reviewing the textbook at length, I did note that it did become easier to follow the text with the omission of colorful fonts and colors, which may also be noted as distraction for some readers. Some more separation between sections, and between text vs. exercises would be appreciated. I do think a more easily navigable e-book would be ideal. I would tend to group this in with sampling distributions. Nothing was jarring in this aspect, and the sections/chapters were consistent. For one. Mine Cetinkaya-Rundel is the Director of Undergraduate Studies and Assistant Professor of the Practice in the Department of Statistical Science at Duke University. As the trend of analysis, students will be confronted with the needs to use computer software or a graphing calculator to perform the analyses. The book has a great logical order, with concise thoughts and sections. This is important since examples used authentic situations to connect to the readers. The book is broken into small sections for each topic. The writing style and context to not treat students like Phd academics (too high of a reading level), nor does it treat them like children (too low of a reading level). The bookmarks of chapters are easy to locate. Reviewed by Monte Cheney, Associate Professor, Central Oregon Community College on 1/15/21, Unless I missed something, the following topics do not seem to be covered: stem-and-leaf plots, outlier analysis, methods for finding percentiles, quartiles, Coefficient of Variation, inclusion of calculator or other software, combinatorics, Technical accuracy is a strength for this text especially with respect to underlying theory and impacts of assumptions. Marginal notes for key concepts & formulae? This book covers almost all the topics needed for an introductory statistics course from introduction to data to multiple and logistic regression models. I found the content in the 4th edition is extremely up-to-date - both in terms of its examples, and in terms of keeping up with the "movements" in many disciplines to be more transparent and considered in hypothesis testing choices (e.g., all hypothesis tests are two-tailed [though the reasoning for this is explained, especially in Section 5.3.7 on one-tailed tests), they include Bayes' theorem, many less common distributions for the introductory level like Bernoulli and Poisson, and estimating statistical power/desired sample size). The resources, such as labs, lecture notes, and videos are good resources for instructors and students as well. It is easy to skip some topics with no lack of consistency or confusion. There are some things that should probably be included in subsequent revisions. The authors limit their discussion on categorical data analysis to the chi square statistic, which centers on inference rather than on the substantive magnitude of the bivariate relationship. For example, it is claimed that the Poisson distribution is suitable only for rare events (p. 148); the unequal-variances form of the standard error of the difference between means is used in conjunction with the t-distribution, with no mention of the need for the Satterthwaite adjustment of the degrees of freedom (p. 231); and the degrees of freedom in the chi-square goodness-of-fit test are not adjusted for the number of estimated parameters (p. 282). This is the most innovative and comprehensive statistics learning website I have ever seen. All of the notation and terms are standard for statistics and consistent throughout the book. Examples stay away from cultural topics. Labs are available in many modern software: R, Stata, SAS, and others. Like most statistics books, each topic builds on ones that have come before and readers will have no trouble following the terminology as they progress through the book. The learner cant capture what is logistic regression without a clear definition and explanation. Things flow together so well that the book can be used as is. No grammatical errors have been found as of yet. For the most part I liked the flow of the book, though there were a few instances where I would have liked to see some different organization. The book was fairly consistent in its use of terminology. These concepts should be clarified at the first chapter. This is a good position to set up the thought process of students to think about how statisticians collect data. 325 and 357). In addition, it is easy to follow. The book is well organized and structured. The sections on these advanced topics would make this a candidate for more advanced-level courses than the introductory undergraduate one I teach, and I think will help with longevity. I see essentially no errors in this book. Overall, the text is well-written and explained along with real-world data examples. The writing could be slightly more inviting, and concept could be more readily introduced via accessible examples more often. The interface is great! Try Numerade free. Search inside document . Ideas about unusual results are seeded throughout the early chapters. At first when reviewing, I found it to be difficult for to quickly locate definitions and examples and often focus on the material. From what I can tell, the book is accurate in terms of what it covers. I think that the first chapter has some good content about experiments vs. observational studies, and about sampling. I did not see any inaccuracies in the book. The content of the book is accurate and unbiased. This is a free textbook for a one-semester, undergraduate statistics course. Reads more like a 300-level text than 100/200-level. The cons are that the depth is often very light, for example, it would be difficult to learn how to perform simple or multiple regression from this book. Percentiles? Perhaps an even stronger structure would see all the types of content mentioned above applied to each type of data collection. The organization is fine. More color, diagrams, etc.? The text is easily and readily divisible into subsections. The structure and organization of this text corresponds to a very classic treatment of the topic. OpenIntro Statistics offers a traditional introduction to statistics at the college level. This is sometimes a problem in statistics as there are a variety of ways to express the similar statistical concepts. The statistical terms, definitions, and equation notations are consistent throughout the text. The introduction of jargon is easy streamlined in after this example introduction. The approach is mathematical with some applications. The prose is sometimes tortured and imprecise. Each topic builds on the one before it in any statistical methods course. The definitions are clear and easy to follow. Reviewed by Bo Hu, Assistant Professor, University of Minnesota on 7/15/14, This book covers topics in a traditional curriculum of an introductory statistics course: probabilities, distributions, sampling distribution, hypothesis tests for means and proportions, linear regression, multiple regression and logistic There are sections that can be added and removed at the instructors discretion. Most essential materials for an introductory probability and statistics course are covered. There are two drawbacks to the interface. The sections seem easily labeled and would make it easy to skip particular sections, etc. The consistency of this text is quite good. The interface is fine. There were some author opinions on such things as how to go about analyzing the data and how to determine when a test was appropriate, but those things seem appropriate to me and are welcome in providing guidance to people trying to understand when to choose a particular statistical test or how to interpret the results of one. The approach is mathematical with some applications. On occasion, all of us in academia have experienced a text where the progression from one chapter to another was not very seamless. The Guided Practice problems allow students to try a problem with the solution in the footnote at the bottom. In other cases I found the omissions curious. I wish they included measures of association for categorical data analysis that are used in sociology and political science, such as gamma, tau b and tau c, and Somers d. Finally, I think the book needs to add material on the desirable properties of statistical estimators (i.e., unbiasedness, efficiency, consistency). Complete visual redesign. read more. Overall, the book is heavy on using ordinary language and common sense illustrations to get across the main ideas. This book does not contain anything culturally insensitive, certainly. Also, non-parametric alternatives would be nice, especially Monte Carlo/bootstrapping methods. Also, grouping confidence intervals and hypothesis testing in Ch.5 is odd, when Ch.7 covers hypothesis testing of numerical data. While to some degree the text is easily and readily divisible into smaller reading sections, I would not recommend that anyone alter the sequence of the content until after Chapters 1, 3, and 4 are completed. Introduction The book covers the essential topics in an introductory statistics course, including hypothesis testing, difference of means-tests, bi-variate regression, and multivariate regression. The texts includes basic topics for an introductory course in descriptive and inferential statistics. However, it would not suffice for our two-quarter statistics sequence that includes nonparametrics. The later chapters on inferences and regression (chapters 4-8) are built upon the former chapters (chapters 1-3). The chapters are well organized and many real data sets are analyzed. There are distracting grammatical errors. Reviewed by Casey Jelsema, Assistant Professor, West Virginia University on 12/5/16, There is one section that is under-developed (general concepts about continuous probability distributions), but aside from this, I think the book provides a good coverage of topics appropriate for an introductory statistics course. David M. Diez, Harvard School of Public Health, Christopher D. Barr, Harvard School of Public Health, Reviewed by Hamdy Mahmoud, Collegiate Assistant Professor, Virginia Tech on 5/16/22, This book covers almost all the topics needed for an introductory statistics course from introduction to data to multiple and logistic regression models. The approach of introducing the inferences of proportions and the Chi-square test in the same chapter is novel. It appears smooth and seamless. (e.g., U.S. presidential elections, data from California, data from U.S. colleges, etc.) The format is consistent throughout the textbook. I have not noted any inconsistencies, inaccuracies, or biases. The index is decent, but there is no glossary of terms or summary of formula, which is disappointing. The final chapter (8) gives superficial treatments of two huge topics, multiple linear regression and logistic regression, with insufficient detail to guide serious users of these methods. This text covers more advanced graphical su Understanding Statistics and Experimental Design, Empirical Research in Statistics Education, Statistics and Analysis of Scientific Data. Chapter 7 and 8 cover the linear , multiple and logistic regression. There are no proofs that might appeal to the more mathematically inclined. Christopher D. Barr is an Assistant Research Professor with the Texas Institute for Measurement, Evaluation, and Statistics at the University of Houston. Probability is optional, inference is key, and we feature real data whenever . For a Statistics I course at most community colleges and some four year universities, this text thoroughly covers all necessary topics. The colors of the font and tables in the textbook are mostly black and white. Therefore, while the topics are largely the same the depth is lighter in this text than it is in some alternative introductory texts. It is clear that the largest audience is assumed to be from the United States as most examples draw from regions in the U.S. The language seems to be free of bias.
