WHAT WE DID HOW WE DID IT SO WHAT

By looking at the raw data and adding up all the different types of bugs found, we thought that there was a real difference between the newly burned forest and the old burn.

 

However, our T-Test showed that we could be 40% wrong. We found out that appearances can be deceiving.
