But the normal distribution is 1 over, this is how it's normally written, the standard deviation times the square root of 2 pi times e to the minus 1 half. Well, I like to write it this way. It's easier to remember. Times whatever value we're trying to get minus the mean of our distribution divided by the standard deviation of our distribution squared. And so if you think about it, actually, this is a good thing to just notice right now. This is how far I'm from the mean, and we're dividing that by the standard deviation of whatever our distribution is. And this is a preview of actually a normal distribution that I've plotted.
