Hello,

I have some data that I have collected, and there is a fairly large
number of data points (900). The way the data is recorded is like this:

172.5 16
172.6 16
172.7 36

and so on. I figured out how to average the values using the
sumproduct() function, but how can I calculate the stdev of the values
without having 900 cells filled with individual data points?

Thanks,

Monte
