Ideally you have collected your own data. However, you can use some data that we collected by clicking here, and downloading the program boyledat in the usual way. There have been numerous problems downloading programs for TI graphing calculators using this method. If it works, it is very clean. Sometimes, however, it doesn't work. In that case we can fall back on an older method, uuencoding, that is less user-friendly but more reliable. Click here for more information about this method.
