I skimmed over your slides, and here are my collected random thoughts:
Very interesting
You need more graphics. I know it's sooo tempting to do much with text, but it's much nicer to look at if you include more graphics. (Update: much better now).
I don't know how good the math-fu of your audience is, but you try to assume as little as possible. For example when you define Var(X), show some graphs from curves with high and low variance. Much easier to imagine for a non-math-geek
Since you declared your talk to be a tutorial, I'd suggest picking one example, and apply the various techniques against that same example. Give the people something familiar to cling to if they feel lost
3 hours is much. Very much. Perhaps too much. My usual lectures (as a student) are 1.5h, and I'm nearly alway glad when they're over. So whatever you do, don't talk for three hours. Do something else in the mean time (show some graphs and shut up for a few minutes, or whatever; I don't really have a good idea what to do, just what not to do)
