PL-300: Preparing Data for Visualizations in Power BI

A vital step between gathering data and creating a report or visualization from it is transforming it into a cohesive form. Use this course to gain hands-on experience in transforming raw data for visualizations. Practice combining related data into a single table. While doing so perform a preliminary analysis of the data so you can imagine what visualizations can be created from it. Next combine data from several files into a single table and conduct several transformations from aggregating data to filtering out unnecessary rows. Finally build a simple column chart visual from the contents of a Power BI table. While doing so identify the different storage modes in Power BI and how they affect your visuals. Upon completion youll be able to prepare data for visualization using a variety of transformations.
