Computer lab Wed. 9/16

Today's class activity is a spreadsheet lab called "Bicycle Rides." Here are all the files you will need for the lab. (The online version of the directions file says "September, 2007" but we are doing an identical lab in 2009.)

You will be able to finish most or all of this lab during the class period, but whatever work remains should be done as homework between now and Friday. On Friday, I will collect the printout you are told to make at the end of the lab.
