Hi, i'm trying to get a bell curve graph with a STDEV of about 5 and a mean
of 13.8. I tried graphing the 1, 2, and 3 stdev above and below the mean and
that didn't work. I just noticed this tutorial
http://www.tushar-mehta.com/excel/ch...tion/index.htm,
however i'm unsure why i have to use -4. I want the mean of 13.8 to show up
on my graph. Any ideas? Thank you!
