Open the Tallest Buildings - Calculated Columns.pbix file in the folder shown above and switch to the Table view of the Building table.
You can see the data in the model by switching to the Table view.
From the ribbon choose Table tools | New column to create a new calculated column.
The formula bar will be activated, ready for you to type your formula.
Change the name of the column to Total floors.
Edit the text on the left of the = sign to give your column a name.
Write a formula to add together the values of the Floors above ground and Floors below ground columns and press Enter to complete the calculation.
The column of answers appears at the right hand side of the table.
Create a new calculated column called Average floor height which divides the Height m column by the Floors above ground column. You could do this using the division operator:
Column Name = Value to Divide / Value to Divide By
Or using the DIVIDE function:
Column Name = DIVIDE( Value to Divide, Value to Divide By )
Whichever technique you choose, you should end up with a new column of messy-looking numbers.
Perhaps a few too many decimal places!
Use the Column tools tab of the ribbon to display the answers with two decimal places.
Two decimal places should be enough.
Switch to the Report view of the report and add a table visual which displays the columns shown in the diagram below:
You can sort the table by clicking on a column header.
Save the file as The Floors the limit.pbix
