MY DISPLAY IS PUTTING UP WEIRD AVERAGES I DON'T KNOW WHAT THEY MEAN

2009 Chrysler PT Cruiser • 57,000 miles

I have a 2009 Chrysler PT Cruiser. It has a trip computer that displays information such as "miles until empty", and "average MPG". When it shows the average MPG I was wondering what exactly IS "average MPG" and how does the computer calculate this?

It compares fuel usage to tire rotation.
