Are you good at math/ statistics?

The probability that a person recovers from a certain disease is .8

suppose 20 people contract this disease.

What is the probability that...

A: exactly 14 recover?

B: at most 16 recover?

You have to figure that out using a bell curve.....Probably N-curve (normal distribution curve).

I hate statistics. It's not real math. It's all based upon curves that are just sort of seen to work.

****ing aweful aweful field of study.

Personally, I think that calling Stats "Math" is degrading to mathmatics.

inorite? if you think about the problem logically, it doesn't work! its like going around your elbo to get to your ask.

 

[seedubs1 10+ year member]

No.....It makes sense. You just have to find out where along the bell curve the 16% and 14% are, and then integrate the curve to find the area under the curve that you want in order to find the percentage probability that it will happen as predicted.

I just think Stat's as a subject is bull shit, because none of the curves and formulas are derived from mathmatical things. They are just theories that are seen to work. There is no proof that they work other than observation.

It's not real math. Real math is unquestionable.
