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.

The aim of this exercise is to divide staff up into 3 bands as follows:

Year of date of birth Description
Up to 1952 Old
Up to 1983 Middle-aged
Anything else Young

You should then use this to get a pivot table showing the average quantiy of goods in each transaction by age category:

Quantity by age band

There isn't much difference, making one wonder whether this is genuine data, or just randomly generated numbers? Surely Wise Owl wouldn't stoop so low?

 

To start, if you haven't already done so run the script in the above folder to generate the MAM database (not for commercial use or copying).

Now import the tblStaff, tblPos and tblTransaction tables.  In the staff table, create two new calculated columns:

Column name What it should contain
BirthYear The year in which this person was born.
AgeBand A verdict on the person's age, using the table above.

Use either a nested IF function to get the age band, or else (better) the SWITCH function. 

Use this information to derive the pivot table at the start of this exercise.

Save your workbook as Age bands, then close it down.
