One of things that I have found to be a disappointed with the US education system is lack of statistics courses in High School. In most cases, the extent of stats/prob education is limited to AP Statistics, which most students will not take and probably scares off many otherwise bright students because of the "AP".

I find this particularly troubling since I remember as a student that my peers would constantly complain about math courses using the rationale "Am I ever going to really use this?". Both sides are arguable for certain subjects (I can't remember the last time I really used trigonometry, but I do think that learning it helped me to reason better in other domains). However, I find it troubling that statistics is not mandatory/highly encouraged, yet it is something that applies to an incredible amount of everyday activities.
