Calculating STDEV and other Calcs based on another cells value


S

Scott

Hello,

I am trying to calculate a standard deviation on a column if another column
contains a certain value. I have been able to calculate the average using
the AverageIFS function, but can't find a way to do it for the stdev
function. For example, if there are 3 people throwing a base ball and I have
entered 20 data points for each. I would like to calculate the standard
deviation based on if the name equals "Joe, "Bob" or "Scott".

Thanks,

Scott

Names in the range A1:A10
Numeric values in the range B1:10

Entered as an array** :

=STDEV(IF(ISNUMBER(MATCH(A1:A10,{"joe","bob","scott"},0)),B1:B10))

** array formulas need to be entered using the key combination of
CTRL,SHIFT,ENTER (not just ENTER)

=STDEV(IF((Team="Pirates")*(ISNUMBER(MATCH(Pitcher,{"joe","bob","scott"},0))),B1:B10))

Where Team and Pitcher are named ranges.

Don't forget to array enter!
