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.

If you haven't already done so, run the SQL script in the above folder (copying and commercial use prohibited) to generate a database called MAM.

Create a new workbook, and in this a data model similar to this one:

As long as you have these two tables, the details aren't important.

Create a pivot table showing total quantity sold per product:

So far, so easy!

Now create and display two calculated fields, using the CALCULATE function:

1. One which shows the total quantity sold for goods where the price is £10 or more (call this Expensive); and
2. One which shows the total quantity sold for goods where the price is less than £10 (call this one Cheap).

The final pivot table should look like this:

For each product, it would be worrying if the cheap and expensive columns didn't sum to the total!
