Yes, if you check the subtotal function help, you'll see that function 7 is
stdev and 8 is stdevp. So, for example, you might calculate
=subtotal(7,a2:a200) to calculate the sample standard deviation of the cells
in a2:a200 that passed your filter.

I'm assuming you want your formulas to consider only the rows that pass the
filter. If so, check out the subtotal function; it honors the filter. Ex
=sum(a:a) will always give you the sum of the entire column.
=subtotal(9,a:a) will total those cells in column A that pass the filter.
See the help on the subtotal function to find the other calculations
available in subtotal (min, max, avg, count, etc).

Hi

Can you have a formula that updates when you use a filter?
