Generic science class data table

September 30, 2009

In my physic classes, we do a lot of labs. Students are encouraged to create their own data tables, but many aren't so "linearly" inclined, and have difficulty creating neat tables. I created a generic data table they can use on any lab. Design of the data table Most of our labs require three measurements [...]

The goal [...]
