C'mon now. I'm taking this stats course very fancily named "Design of Industrial Experiments."

Stats...well, it tests my common sense standard at times. For instance, if you have two processes and you take 10 samples from each and one average is higher than the other average, the one with the highest average is the best, right? Seems simple enough.

But no, you have to perform a hypothesis test, because you have to take into account how much the data varies.

But here's the "c'mon now." In the latest homework assignment is a problem about 4 circuit designs that are being tested regarding how much average noise they allow (low is good). Circuit design #1 has an average of 19.2 (19.2 what, you ask--I don't know) and one of the other circuit designs has an average of 79.8. One of the questions was, "Is there a significant difference between any of the circuit designs?"

Well, yeah.

But it took me about a page to show that in stats-speak.
