Hello ddawg09,

Is each column a separate sample or total population, or are the
columns one sample or a population? Is the upper limit Z-score 1 (68%)
or something else?

Sincerely,
Leith Ross


Yeah, each of my 3 columns is separate and so I have to use the
Empirical Formula for all 3. I just wanted to see if there was an
easier way then finding the average and standard dev. and then finding
the % of points in each range.
