You need a minimum screen resolution of about 700 pixels width to see our exercises. This is because they contain diagrams and tables which would not be viewable easily on a mobile phone or small laptop. Please use a larger tablet, notebook or desktop computer, or change your screen resolution settings.
Create a new Power BI report, and load in the data in the above workbook:
The raw data - your task is to massage it into something more presentable!
Use Query Editor to make this data look better:
Some columns have been renamed, while each person's wealth (in billions of dollars) has been extracted - see below for how.
If you need hints on extracting the wealth of each person in billions, one way to proceed is to follow these steps:
|Step||What to do|
|1||Replace the word billions with an empty string.|
|2||Replace the $ symbol with an empty string.|
|3||Convert the resulting column to a whole number.|
Bring the data back into your Power BI report, and use it to create a simple chart:
Create a simple chart just to prove that the billions really are being treated as numbers.
Save this report as But are they happy, then close it down.
