So anyway, I wanted to do that just because I thought it was neat and it's interesting to play around with it, and that way if you see it in any of these other forms in the rest of your life, you won't say, what's that? I thought the normal distribution was this or was this, and now you know. With that said, let's play around a little bit with this normal distribution. So in this spreadsheet, I've plotted normal distribution. You can change the assumptions that are in this kind of a green-blue color. So right now it's plotting it with a mean of 0 and a standard deviation of 4. And I just write the variance here just for your information.
