Flowchart and entropy

Sorry about the quality, if you cant read it the text, the first four diamonds saw "Is it greater than" and then "89, 74, 59, and 44" respectively. The last one says "is it less than 44?" Finally the bottom squares say "Return" and "A, B, C, D, and F" respectively. Otherwise it shouldn't be too hard to read.

Hartley's measure deals with simple yes and no question's to measure information using a log with a base of 2
Shannon's entropy uses a weighted measure using probabilities and a log of base 2.
Both measures remove uncertainty to measure information.

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.
