And just to understand this spreadsheet a little bit better, just because I really want you to play with it and move the, see what happens when, if I make this distribution, the mean was minus 5, now let me make it 5. It just shifted to the right. It just moved over to the right by 5, right? Whoops. I'll use the pen tool. It just moved over to the right by 5. If I were to try to make the standard deviation smaller, we'll see that the whole thing just gets a little bit tighter.
