Tell me /sci/ without any emotional bias:
Which degrees are shit tier
Which degrees are god tier
And I know that mathematics and science knowledge are ALWAYS god tier, which surprises me to some extent. For example, I recently learned econ majors are not doing so well in today's market, I always thought that economics required a broad understanding of mathematics, mainly game theory, but recently learned that is not the case. Medical majors also do not require that much math, which is why more engineering BS's are getting into medical schools these days then pre-med majors. They do better on the MCATs
What the fuck is variance used for?

Hey /sci/, I'm in a probability and statistics class up in Uni. Right now we're working with mean, variance, and standard distribution. I understand the idea of a mean just fine because I've been working with it pretty much all my fucking life. Roll a d6, mean value is 3.5, meaning in the long run if I roll billions and billions of dice, half will be above 3.5 and half will be below. I can also understand standard deviation to a point, it's the average distance for any of those points in the data set from the mean. So where 1 is 2.5 away from the mean, 2 is 1.5 and 3 is 0.5 (and in reverse order of the aforementioned for 4, 5, and 6), the average of those values is 1.5.
Easy shit, I can see the usage for either...
But all I know of variance is how to calculate it. What the gog damned fuck am I supposed to use it for though?
