Standard Deviation Chart
You can calculate standard deviations, and you can chart numbers. What
precisely is a "standard deviation chart"? - Jon ------- Jon Peltier, Microsoft Excel MVP Peltier Technical Services, Inc. http://PeltierTech.com/WordPress/ _______ "Thomas M." wrote in message ...

Standard Deviation Chart
It's been years since I came across a situation where I thought doing a
standard deviation calculation and charting the results would be the way to go. However, I do remember one request from years back where my boss wanted two bell-shaped curves on the same report. I was working for a medical case management company at the time, and the x-axis was to show numerical values for diabetes patients where the higher the number the healthier the person (in over simplified terms). The first bell-shaped curve was to show the range that people fell into when they first entered the diabetes management program, and the second curve was to show the range that those same patients fell into after being in the program for a given period of time. He wanted the area under each curve to be entirely colored in. I was working with Excel 97 at the time, and I just seem to remember that I could not find an easy way to produce such a chart. --Tom "Jon Peltier" wrote in message ...

Ah, if you had said bell curve, I would have instantly known. My colleague

Standard Deviation Chart
Oh, yeah, sorry. For some reason I have always thought about that the
approach for that particular issue being one in which you calculate the mean for the population and then break the population down into groups of +/- 1 standard deviation, +/- 2 standard deviations, etc. So I've just always thought of it as a "standard deviation" chart. But you're right, the term "bell curve" is probably a more readily understandable description. I just noticed your latest reply, so I haven't yet had a chance to review in detail the article that you linked to in the reply. However, just glancing at the article it looks like it's what I need. I'll try to take a look at it this weekend. Thanks for the help. --Tom "Jon Peltier" wrote in message ... Ah, if you had said bell curve, I would have instantly known.

Standard Deviation Chart
I checked out the link that you posted. I used the first method to create a
chart with a bell curve. I then added a second data series using a different mean and added that data series to the chart. The result was one chart containing two bell curves, which is what I wanted. However, I could not get the second method to work. I followed the instructions to the letter, but when I try to enter the formulas for the X and Y values in the data series, I get an message indicating, "The formula you typed contains an error." I think that the article is written for Excel 2003, whereas I'm using 2007, so maybe I am not making the translation correctly or something. --Tom "Jon Peltier" wrote in message ...
