Standard Deviation

[Soccerboy83]

Is it possible to form an equation that will give me a standard deviation for
all numbers above a certain value. I know there are SUMIF and COUNTIF
formulas and if you want the average you actually have to do (SUMIF/COUNTIF)
because there is no AVERAGEIF. I guess what i am asking is if there is a way
to do a standard deviation for only a certain range of numbers.

Assuming that A2:A100 contains the data, and that C2 contains the value
of interest, try the following formula that needs to be confirmed with
CONTROL+SHIFT+ENTER...

=STDEV(IF($A$2:$A$100>C2,$A$2:$A$100))
