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 Desktop file, and load data from both worksheets in the Excel workbook in the above folder.

In Query Editor, solve this problem:

Row headers

Make the first row of the table into the row headers for it.


Create a relationship between the two tables:

Relationship between tables

The two tables weren't automatically linked because the field names aren't the same.

Now create a slicer allowing you to show only certain types of houses:

Slicer for house type

Choose to show detached houses - no terraced houses for this exercise!


Now create a map showing the number of sales of this house type for our September 2016 data by location:

Locations in USA

Things aren't looking good - Power BI Desktop is not recognising that the locations are all in the UK.


To get your map to load more quickly, apply a filter to it so that you only see house sales where the sales price was at least £1,000,000.

Create an additional column in the main table suffixing , UK onto the end of each location, and use this instead in your map:

Chart and slicer

Much better!

Save this as North South divide, then close down the Power BI instance containing it.
