I use this book in teaching and I did not find any issues with accuracy, inconsistency, or biasness. A teacher can sample the germane chapters and incorporate them without difficulty in any research methods class. 7. The book uses relevant topics throughout that could be quickly updated. My interest in this text is for a graduate course in applied statistics in the field of public service. The topics are not covered in great depth; however, as an introductory text, it is appropriate. The book started with several examples and case study to introduce types of variables, sampling designs and experimental designs (chapter 1).

OpenIntro Statistics 4th Edition by David Diez, Christopher Barr, Mine etinkaya-Rundel. Jargon is introduced adequately, though. though some examples come from other parts of the world (Greece economics, Australian wildlife). You can check your reasoning as you tackle a problem using our interactive solutions viewer. For example, income variations in two cities, ethnic distribution across the country, or synthesis of data from Africa. 
These examples and techniques are very carefully described with quality graphical and visual aids to support learning. In my opinion, the text is not a strong candidate for an introductory textbook for typical statistics courses, but it contains many sections (particulary on probability and statistical distributions) that could profitably be used as supplemental material in such courses. 
It is difficult for a topic that in inherently cumulative to excel at modularity in the manner that is usually understanding. There are separate chapters on bi-variate and multiple regression and they work well together. #. I was able to read the entire book in about a month by knocking out a couple of subsections per day. This is a statistics text, and much of the content would be kept in this order. Great job overall. It includes too much theory for our undergraduate service courses, but not enough practical details for our graduate-level service courses. The regression treatment of categorical predictors is limited to dummy coding (though not identified as such) with two levels in keeping with the introductory nature of the text. From what I can tell, the book is accurate in terms of what it covers. I did have a bit of trouble looking up topics in the index - the page numbers seemed to be off for some topics (e.g., effect size). I see essentially no errors in this book. I find this method serves to give the students confidence in knowing that they understand concepts before moving on to new material. It begins with the basics of descriptive statistics, probability, hypothesis test concepts, tests of numerical variables, categorical, and ends with regression. The first chapter addresses treatments, control groups, data tables and experiments. 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 do not think that the exercises focus in on any discipline, nor do they exclude any discipline. Similar to most intro The authors present material from lots of different contexts and use multiple examples. 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. The approach of introducing the inferences of proportions and the Chi-square test in the same chapter is novel. There are lots of graphs in the book and they are very readable. They have done an excellent job choosing ones that are likely to be of interest to and understandable by students with diverse backgrounds. It has scientific examples for the topics so they are always in context. I think it would work well for liberal arts/social science students, but not for economics/math/science students who would need more mathematical rigor. I found virtually no issues in the grammar or sentence structure of the text. You can also find solutions immediately by searching the millions of fully answered study questions in our archive. This could be either a positive or a negative to individual instructors. 191 and 268). 5. The examples are up-to-date, but general enough to be relevant in years to come or formatted appropriately so that, if necessary, they may be easily replaced. The text is free of significant interface issues. Summarizing data. I would consider this "omission" as almost inaccurate. 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 topics all proceed in an orderly fashion. Teachers might quibble with a particular omission here or there (e.g., it would be nice to have kernel densities in chapter 1 to complement the histogram graphics and some more probability distributions for continuous random variables such as the F distribution), but any missing material could be readily supplemented. There are lots of great exercises at the end of each chapter that professors can use to reinforce the concepts and calculations appearing in the chapter. There are also a number of exercises embedded in the text immediately after key ideas and concepts are presented. The resources on the website also are well organized and easy to access and download. The definitions are clear and easy to follow. The consistency of this text is quite good. The book covers familiar topics in statistics and quantitative analysis and the presentation of the material is accurate and effective. Reviewed by Emiliano Vega, Mathematics Instructor, Portland Community College on 12/5/16, For a Statistics I course at most community colleges and some four year universities, this text thoroughly covers all necessary topics. 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." Some of these will continue to be useful over time, but others may be may have a shorter shelf life. 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. 
In addition, some topics are marked as special topics. I was sometimes confused by tables with missing data or, as was the case on page 11, when the table was sideways on the page. Solutions Manuals are available for thousands of the most popular college and high school textbooks in subjects such as Math, Science (. The pros are that it's small enough that a person can work their way through it much faster than would be possible with many of the alternatives. Navigation as a PDF document is simple since all chapters and subsection within the table of contents are hyperlinked to the respective section. Choosing the population proportion rather than the population mean to be covered in the foundation for inference chapter is a good idea because it is easier for students to understand compared to the population mean. In particular, the malaria case study and stokes case study add depth and real-world meaning to the topics covered, and there is a thorough coverage of distributions. The code and datasets are available to reproduce materials from the book. The approach is mathematical with some applications. The examples will likely become dated, but that is always the case with statistics textbooks; for now, they all seem very current (in one example, we solve for the % of cat videos out of all the videos on Youtube). In other cases I found the omissions curious. The text needs real world data analysis examples from finance, business and economics which are more relevant to real life. Chegg Study Expert Q&A is a great place to find help on problem sets and Statistics and Probability study guides. Percentiles? read more. Most essential materials for an introductory probability and statistics course are covered. Also, for how the authors seem to be focusing on practicalities, I was somewhat surprised about some of the organization of the inference sections. The graphs and tables in the text are well designed and accurate. For example, types of data, data collection, probability, normal model, confidence intervals and inference for I do think a more easily navigable e-book would be ideal. WebOpenIntro Statistics 4.1: Variability in Estimates 4.1 Identify the parameter, Part I. Labs are available in many modern software: R, Stata, SAS, and others.

They authors already discussed 1-sample inference in chapter 4, so the first two sections in chapter 5 are Paired Data and Difference of Means, then they introduce the t-distribution and go back to 1-sample inference for the mean, and then to inference for two means using he t-distribution. Any significant rearranging of those sections would be incredibly detrimental to the reader, but that is true of any statistics textbook, especially at the introductory level: Earlier concepts provide the basis for later concepts. The text meets students at a nice place medium where they are challenged with thoughtful, real situations to consider and how and why statistical methods might be useful. It is certainly a fitting means of introducing all of these concepts to fledgling research students.

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 offers companion data sets on their website, and labs based on the free software, R and Rstudio. The purpose of offering the data cards to the customers is that the collect and maintain the data and using the data to target the customers and The book is very consistent from what I can see. If anything, I would prefer the book to have slightly more mathematical notation. Normal approximations are presented as the tool of choice for working with binomial data, even though exact methods are efficiently implemented in modern computer packages. Refer to the contingency table in problem 1.1 of the textbook to answer the questions. Overall, this is the best open-source statistics text I have reviewed. There is more than enough material for any introductory statistics course. Try However, when introducing the basic concepts of null and alternative hypotheses and the p-value, the book used different definitions than other textbooks. To many texts that cover basic theory are organized as theorem/proof/example which impedes understanding of the beginner. The chapter is about "inference for numerical data". Chapter4 (foundations of inference), chapter 5 (inference of numerical data) and chapter 6 (inference of categorical data) provide clear and fresh logic for understanding statistics. These blend well with the Exercises that contain the odd solutions at the end of the text. It does a more thorough job than most books of covering ideas about data, study design, summarizing data and displaying data. Overall it was not offensive to me, but I am a college-educated white guy. The text covers all the core topics of statisticsdata, probability and statistical theories and tools. the U.K., they may not be the best examples that could be used to connect with those from non-western countries. For example, I can imagine using pieces of Chapters 2 (Probability) and 3 (Distributions of random variables) to motivate methods that I discuss in service courses. The formatting and interface are clear and effective. The supplementary material for this book is excellent, particularly if instructors are familiar with R and Latex. The chapter on hypothesis testing is very clear and effectively used in subsequent chapters.
