Mike and Kevin,
Thanks for your replies - I'll set up a test case and see if the histogram,
plus a mean and standard deviation provide the consensus I'm looking for.
FYI, John Walkenback discribes a normal distribution/histogram combination
chart in his book "Excel Charts" (pg. 281), but he's a little sketchie on
its construction. This may a good model, but will take some work to figure
out.
Regards,
Phil

I agree that it's usually a good idea to first "look at the data." And, if
you want a better histogram, arrange the fifteen values in a column on a
worksheet, and use my free add-in to obtain the frequency distribution and
histogram. Visit the "Better Histogram" page at www.treeplan.com.
