I did really well in Uni-stats. But in fairness I was going out with a virgin-genius and so my study habits were directly correlated with my desire to invade her blonde Spark. (see what i did there?)
But even after spending 2 months in rehab doing nothing but studying Poisson Distributions and working out with Fentanyl addicts, I found myself struggling..
It's not the math; that's elementary at best. It's the conceptional A|B clauses that always throw me.
It's a brain f*ck. And the older I get, although i get much sexier, my stats skills diminish.
Long story short, before delving into any of this data science stuff you need to learn your stats. Give yourself a good couple of months of dedication.
Even better, get yourself arrested for some inoffensive non-violent crime and do your time in the library.
