Before you can do this exercise, you'll need to download and unzip this file (if you have any problems doing this, click here for help).

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.

Open the Power BI report in the above folder.  The data shows the number of completed tests by exam for each month of 2018 from the Wise Owl skills assessment site:

Skills assessment data

For example, 82 tests were completed for Word in October 2018.

Create a waterfall chart showing for each month the two leading causes of a change in the number of tests taken (with everything else lumped together as Other):

Unsurprisingly, the yellow Other category is often the biggest.

Save this report as May the force be with you, then close it down.
