Data rarely comes in perfect form and often requires manipulation in order to make it truly meaningful. Without the ability to manipulate data, you often cannot extract full meaning from it. In this course, you will explore techniques for manipulating data, beginning with recoding data, derived variables, and data merging and blending. Then you will perform a data merge and a data blend and dig into concatenation and appending. Next, you will focus on imputation, reduction, and aggregation. Finally, you will learn how and why to transpose datasets, how to achieve standardized data formats using data normalization, and how to parse and manipulate strings. This course can be used to prepare for CompTIA Data+ (DA0-001) exam.
