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.

Create a new Power BI report, and load data from the CSV file in the above folder:

Sleep statistics

A log of how long a reasonably imaginary Wise Owl trainer slept in 2021.


Show the hours slept by week (you'll need to remove the date hierarchy to do this):

Sleep by date

REM These figures seem reasonable (this is a joke for old programmers only).


Add a minimum and maximum line, making sure you show the label for each:

Max and min line

You may want to change your scaling, so that the minimum isn't on the bottom axis.

Now add a trend line showing what this person can expect:

Adding trendline

The trend is up: this person is gradually getting more sleep!

If you still have the energy, add a two-month forecast period:

Two-month forecast

There are only 12 months of data, so the forecast is ... uncertain.

Save this report as Greeting the sleep monster, then close it down.
