To me it seems like a wasted unit in my math class.
I think that statistics is the most useful thing you could ever learn in high school, and I'll tell you why.
Can you think of any other mathematics that is used so often to influence public policy? Mark Twain once said "There are three kinds of lies: lies, damn lies, and statistics."
With the way statistics are bandied about by politicians - usually erroneously - I don't see how one could truly be a full-fledged participant in democracy without an ability to sort good statistical reasoning from bad.
