This will test your ability to understand how to input the correct data so that the built-in functions work properly. It will also test your ability to think logically about what your columns and rows of data actually mean in a worksheet.

2. Car Fuel Economy:

This assignment is to help you get more familiar with excel. This also helps you practice finding differences between reliable and non-reliable sources on the internet. You will be creating graphs to analyze data. You'll find that Excel makes a very powerful calculator.
