CompTIA Data+ Study Guide: Exam DA0-001 (Sybex Study Guide)

I couldn’t recommend this book more. It studied it for two weeks and passed my test first try. It got the job done.

This book was instrumental in helping me pass the Data+ exam. I have also been practicing in the field for almost a decade, but this book filled in several knowledge gaps and solidified my confidence in the field.

I bought the Kindle edition of the book. I didn't bother doing the practice tests or using the flashcards as the exam's passing score is 675. This book gets 5 stars because it gets the job done. Skip the exam unless someone else is paying for it. The $239 USD (as of the time I am writing this) can be better spent on data analysis books or online courses.

Questions and answers in multiple chapters contain mistakes. Fixed in the online question bank though. Overall, some content is very confusing, a bit lacking. After multiple attempts to read the chapter and pass the rather limited questionary, it is still not clear which data is duplicated, and which is redundant. It seems the chapter clearly defines this, yet multiple questions contradict the definition. I would like to have at least 40 questions per chapter.

I read it and I passed the CompTIA Data+ exam

Bottom line: if your priority is to learn or review concepts, this book will serve you well. If you're looking more for quizzes and practice tests, I would recommend against this. I found the question bank to be actively detrimental to my understanding and full of errors. The book itself is very good. It clearly explains the concepts for the exam and strikes a good balance between detail and not overwhelming the student. The problem is that the quizzes and practice exams included are not even close to the same quality. Between the questions where the "correct" answer directly contradicts the text, to those where an entirely made-up throwaway choice is somehow the right answer, to those where the explanation refers to a different question than what was asked, there's a massive dropoff in quality from the text itself. The Wiley website where the quizzes and tests are hosted (mandatory signup to access the two full practice tests and flashcards, optional for the chapter quizzes) is ok, although the registration process seems purpose-built to be annoying. Since Data+ is still a new exam as I'm writing this, there aren't a lot of study resources available. Unfortunately, it seems like this study guide was rushed out to try and take advantage of that fairly empty market. Hopefully a future edition fixes the serious flaws of this book, but as of 2022, the built-in evaluations fall far short.

I really enjoyed reading this book. It gave enough understanding on the fundamentals of Data Analytics for the exam. I do agree with other reviewers on the point that the book did not cover some of the topics for the test. Just for this, I'm giving it 4 stars. Hopefully, the authors catch and add them in the future. Even when the book didn't cover the missing ones, I still managed to pass it by some prior knowledge of data, reading the whole book, and watching YouTube videos. Reading the book and watching videos helped tremendously though. It`s still worth buying the book to read but make sure to look at other sources for further clarifications. I liked gaining knowledge on the subject through this.

I bought this book with plans to take the CompTIA Data+ exam. So far I am not enjoying it. The book does not align with CompTIA's objectives because the topics are not arranged in order. When it references figures it does not include the page number it is on and it's likely you've already passed by it. You're forced to go backwards in your reading if you want to refresh your memory. The Review Questions are awful and lack variety. Just about each question starts with a person's name then blah, blah, blah. It's not personalized to the user like a "How would you handle this situation?" type of question would be. I've instead purchased The Official CompTIA Data+ Self-Paced Study Guide (Exam DA0-001) on the CompTIA website.

All good with the book

This book provides foundational information that covers all the main examinable domains for the CompTIA Data+ exam, but extra reading outside the book and completing as many Data+ practice tests is recommended.

I bought this mainly for access to the online learning resources. The book and the Wiley website state clearly that they will issue a PIN to access the additional content. No PIN was provided. No means to access the content was provided. After going round and round between different Wiley webpages for 15 minutes, I requested a return.
