Generally though, the study of statistics is called: Data Management. Or at least that's the course I took in High School involving the study of statistics. Choosing all the hardest courses really paid off tbh.
Abstract Math is the most schizo shit you'll ever study in your life (matrices / unreal numbers). Only course I ever failed absolutely. The smartest kid in my class was a Jew and he understood that shit even though all we did was talk about video games during class the whole time; wtf?
