OT: A two-sample t-test. That is the correct test right? Just did it quickly in excel. I might go back and check it to make sure, but I dont really care too much because it is easy to just look at my data and see that it was a real effect. I had over 100 data points so I can pretty much insure that it wasn't just random.

I took grad level statistics, so hopefully I did it correctly. It has been a couple years though...
