CompTIA Data+: DAO-001 Certification Guide

By: Cameron Dodd

Overview of this book

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.

Understanding the report development process

Let’s talk about the process of actually creating a report. The process may be slightly different depending on the procedures of where you end up working, but this is the general process identified by the experts at CompTIA. For the exam, you will need to know the steps involved in the report creation process, have a general idea of what they mean, and know what order they should be done in. I will point out that for the exam, this process is specifically related to dashboard development, but the concepts have been generalized here to cover all reports Whether we are talking about a dashboard or any other kind of report, except for an ad hoc report, the process will be roughly the same. Ad hoc reports generally have a less formal process because they require a quick turnaround time. The four-step process is as follows:

  1. Create a plan.
  2. Get the plan approved.
  3. Create the report.
  4. Deliver the report.
