Description

The CompTIA Data+ certification exam not only helps validate a skill set required to enter one of the fastest-growing fields in the world, but also is starting to standardize the language and concepts within the field. However, there’s a lot of conflicting information and a lack of existing resources about the topics covered in this exam, and even professionals working in data analytics may need a study guide to help them pass on their first attempt. The CompTIA Data + (DAO-001) Certification Guide will give you a solid understanding of how to prepare, analyze, and report data for better insights. You’ll get an introduction to Data+ certification exam format to begin with, and then quickly dive into preparing data. You'll learn about collecting, cleaning, and processing data along with data wrangling and manipulation. As you progress, you’ll cover data analysis topics such as types of analysis, common techniques, hypothesis techniques, and statistical analysis, before tackling data reporting, common visualizations, and data governance. All the knowledge you've gained throughout the book will be tested with the mock tests that appear in the final chapters. By the end of this book, you’ll be ready to pass the Data+ exam with confidence and take the next step in your career.

Cameron's Certification Guide is fantastic.This guide is straightforward and easily digestible. As someone who has little experience with DB management, but a good understanding of how to Query data, this guide has helped tie multiple loose ends up on how Data is structured and presented. He even provides some common ways that Data can be structured poorly to help keep from making the mistakes of others. The detail in the examples provided are simple and effective. Lots of practice and examples throughout the book to supplement the knowledge. I cannot thank Cameron enough for providing such an insightful piece of work and I have no doubt that it covers everything you would need to take and pass the certification on the first attempt. Thank you Cameron! Wish me luck!

Data is the future, and this is a fantastic guide for essential topics in data science. If you are interested in data science, use this wonderfully written guide to prepare for the Data + exam. When I prepare for exams, I always search for practice exams - these help with confidence and exam readiness. This book has multiple practice exams with really quality questions.

CompTIA Data+: DAO-001 Certification Guide is a wealth of information. Although the entire guide is extremely valuable, I especially appreciated the breakdown of Data Structures, Types and Formats.Cameron Dodd has a thorough way of explaining complex concepts in a way that can easily be understood and remembered. An example is his breakdown of Data Structures, structured vs. unstructured and how they tie to the relational and non-relational databases. The example of the star vs. snowflake schema outlining the pros and cons of each allowed me to better understand when to use each effectively.In true form, Cameron explains the differences between data warehouses, data marts and data lakes (which can be confusing) in such a way a layperson can understand. My only negative feedback is that Cameron prefers Snowflake where I’m an AWS fan myself. ;)
