Honestly I expected it to go over far more advanced topics than these, most of these are covered in the last year of high school over here.

Opening sentence: The goal of this document is to present an introduction to probability and markets in what we hope is a fairly intuitive and accessible way.
- Utkarsh_Mood 3y agoright no I guess thats not what I meant to say, rather that I expected any learning material from Jane Street(which has some really rigorous interviews) to give a better heads-up to the type of thinking thats required to do well in those interviews.
- andsoitis 3y ago> type of thinking thats required to do well in those interviews They have a whole page dedicated to that: https://www.janestreet.com/join-jane-street/interviewing/ https://www.janestreet.com/join-jane-street/interviewing/ Attention to detail and clear communication, including good grammar and spelling, are probably important.
- elteto 3y agoBasic reading and comprehension is not covered in his last year of high school it seems.

- dwater 3y agoI teach post-grad stats classes in the US, with no real prerequisites besides a Bachelor's degree. Most but not all of my students have passed a college level stats class that covered these concepts, and maybe half of those did not retain a true understanding of these concepts by the time they got to my classroom. In my experience, math is the least like/most hated of the core subjects, and stats is one of the least liked/most feared math subjects.
- Solvency 3y agoWhat makes statistics seems so daunting to the average student over, say, discrete mathematics? I feel like statistics has so many immediately obvious real world use cases and useful analogies to help frame it (die rolls, etc).
- Foobar8568 3y agoEasy to get things wrong from the wrong intuition or understanding of the problem. Cross mathematic discipline etc. But I feel that most applications just need high school math.
- kqr 3y agoThe very idea underlying statistics (that we can learn something useful from a class of events by ignoring specifically that which makes them different from each other) is a very recent invention -- only a few hundred years old -- and it's still counter-intuitive to a lot of people. Ask people to predict whether the Jones' have a dog and they'll start asking questions about the specifics of the Jones', like do they have children, do they live in the suburbs, have they always wanted a dog, etc. Then they try to construct a narrative based on "logical" conclusions. When the right approach might be to ask "what's the background rate of dog ownership in the Jones' country of residence?" But that takes ignoring the specifics, and that doesn't come easily to people. It took several millennia for anyone to realise it could be useful.

This is the core idea of Bayesian statistics. You fall back to the background rate only if you have no ability to access more pertinent facts.
- danielmarkbruce 3y agoDespite it being "covered" in many places, few otherwise intelligent people actually grok this stuff or have any real intuition for it.
