This book does not do a particularity good job of explaining statistics and econometrics to people new to these topics, which is the purpose of the book.The problem is that the authors use language and reasoning that I feel only people with an already decent grasp of statistics will easily understand. It results in explanations that feel less intuitive than those given in your regular beginner's textbook on econometrics and statistics. So if you are a historian or social scientist I would much rather suggest using textbooks such as 'Using Econometrics' by Studenmund, 'Principles of Econometrics' by Hill et al., or 'Introductory Econometrics' by Wooldridge. They go somewhat deeper regarding the mathematics used but are much easier to actually follow in your head.
The written explanations of the quantitative models and techniques under consideration are excellent. However, this book has two fatal problems. The first is that the online data sets (which you must download and work with on a computer). At least one of them is incomplete (there is some data missing). The second is that there are a series of exercises for students to work their way through, but no answers are provided! Immensely stupid and it means you end up simply taking a guess at every question with no way of knowing whether you have the right answer.
