My first Excel (Lab 9)

Yes, its odd, this is my very first time actually using excel for anything useful. And once I figured out all the little intricacies, its quite a powerful device. I learned that linear regression was a statistical analysis of data, I had previously known how to calculate slopes and intercepts, but I did not know about r and how to calculate it and use it for linear regression. This is a powerful tool in inductive modeling for it shows the difference between what is expected (ideal) and what is actual.
