STDEV can take up to 30 separate arguments. If you have a contiguous range
(such as A1:C99), than counts as one argument.

I have a datasheet with data of more than 30 people. I want to calculate
the
standard deviation, but the Help function of Excel tells me that Stdev is
used for a group of max 30 persons. What function should I use to
calculate
the standard deviation for a group of more than 30 people?
