Stats all the way!
What can you do with mechanics anyway? Make bridges? Make buildings? Wow. Like, my little sister could do that, dude.
With Stats, if you are extra-specially good, you might be able to calculate the probability of your computer crashing during normal use, or maybe even the probability of it NOT crashing. I've heard that if you get to degree level, you might even be taught how to draw a stem and leaf diagram.
